What is Equality?

Equality is the principle that all people are created equal and should have equal rights, opportunities, and treatment regardless of their gender, race, ethnicity, religion, social status, or any other characteristic. It is a fundamental human right and a cornerstone of modern democratic societies, ensuring that every person has an equal chance to succeed, thrive, and participate in social, economic, and political life. Equality is not just about treating everyone the same; it also recognizes and respects differences and promotes diversity, inclusion, and respect for human dignity.

At its core, equality means that all individuals have the same basic rights and opportunities, such as the right to life, liberty, and the pursuit of happiness, the right to vote, the right to work, the right to education, and the right to access healthcare. It also means that everyone should be treated fairly and without discrimination, regardless of their background, beliefs, or physical characteristics.

Equality is essential for creating a just and harmonious society where everyone is valued and respected. When individuals are treated equally, they are more likely to feel a sense of belonging and trust in their community, which can foster social cohesion and reduce social tensions. It also helps to promote a more diverse and inclusive society, where individuals from different backgrounds can contribute their unique perspectives and talents to the benefit of all.

However, achieving equality is not always easy, and there are many challenges and barriers that must be overcome. Discrimination and prejudice continue to exist in many forms, and there are often structural inequalities that prevent certain groups from accessing the same opportunities and resources as others. For example, women, people of color, LGBTQ+ individuals, and people with disabilities often face barriers to education, employment, and political representation, which can limit their ability to succeed and thrive.

To address these challenges and promote equality, it is essential to implement policies and practices that promote fairness, inclusion, and diversity. This can involve measures such as affirmative action programs, anti-discrimination laws, and social welfare programs that provide support for disadvantaged groups. It can also involve education and awareness-raising campaigns that promote respect and understanding for different cultures, beliefs, and lifestyles.

Another critical aspect of promoting equality is addressing structural inequalities that perpetuate social and economic disparities. This can involve measures such as increasing access to education and job training, promoting equal pay for equal work, and providing affordable healthcare and housing. It can also involve supporting small businesses and community development projects that help to create jobs and stimulate local economies.

Finally, promoting equality also requires a commitment to social justice and human rights. This involves advocating for the rights of marginalized groups and working to eliminate systems of oppression and inequality. It can also involve promoting democracy and civil rights, ensuring that everyone has a voice in their community and government.

In conclusion, equality is a fundamental human right that is essential for creating a just, inclusive, and harmonious society. It requires a commitment to fairness, inclusion, and diversity, as well as addressing structural inequalities and promoting social justice and human rights. While there are many challenges to achieving equality, it is essential that we continue to work towards this goal, recognizing that every person has the right to be treated with dignity and respect, regardless of their background or characteristics.

The Communist Manifesto: Key Concepts

The Communist Manifesto is a political document written by Karl Marx and Friedrich Engels, first published in 1848. It outlines the basic principles of communism and lays out the goals and methods of the Communist movement. The document is divided into four sections: the Bourgeoisie and Proletariat, Proletarians and Communists, Socialist and Communist Literature, and finally, the position of the Communists in relation to the various existing opposition parties.

The first section of the Communist Manifesto begins by describing the historical development of class struggle between the bourgeoisie and the proletariat. The bourgeoisie, or the ruling class, emerged from the decline of feudalism and the rise of industrialization, while the proletariat, or working class, emerged as a result of the capitalist mode of production. The document argues that the capitalist system is inherently exploitative, with the bourgeoisie profiting off of the labor of the proletariat, who are paid wages that are always lower than the value of the goods they produce.

The second section of the manifesto outlines the goals and methods of the Communist movement. The Communist Manifesto argues that the only way to overcome the exploitative nature of capitalism is through the abolition of private property and the establishment of a classless society. In a communist society, the means of production would be owned and controlled by the workers themselves, rather than by a small group of capitalists. This would eliminate the exploitation of the working class and create a society in which everyone had an equal stake in the production and distribution of goods.

The third section of the manifesto addresses the various forms of socialism and communism that existed at the time of its writing. The authors argue that many of these movements were misguided, as they failed to recognize the importance of the class struggle and the need for the proletariat to take control of the means of production. They also critique the ideas of various other socialist and communist thinkers, including Pierre-Joseph Proudhon, Louis Blanc, and Ferdinand Lassalle.

The final section of the manifesto lays out the position of the Communist movement in relation to other political parties and movements. The authors argue that the Communist movement represents the true interests of the proletariat, and that other parties and movements that claim to represent the working class are merely trying to maintain the status quo. They argue that the Communist movement should not align itself with any other political party or movement, as doing so would compromise its principles and goals.

Overall, the Communist Manifesto is a call to action for the proletariat to rise up and overthrow the bourgeoisie, and to establish a classless society in which everyone has an equal stake in the production and distribution of goods. It has been hugely influential in shaping political movements and ideologies throughout the world, and its ideas continue to be debated and discussed today.

Essay Concerning Human Understanding: Key Concepts

An Essay Concerning Human Understanding is a philosophical work by the English philosopher John Locke, published in 1689. The book is considered one of the foundational texts of modern Western philosophy and is widely regarded as a masterpiece of philosophical writing. It presents a comprehensive account of the nature and limits of human knowledge and understanding, as well as the role of experience and reason in human cognition.

The main argument of the Essay Concerning Human Understanding is that all knowledge is derived from experience. Locke rejects the idea of innate ideas or knowledge, arguing that the mind at birth is a blank slate, or tabula rasa. He contends that all knowledge and ideas come from sensory experience, and that our understanding of the world is based on the associations and patterns that we observe in the natural world.

Locke divides human knowledge into two categories: intuitive knowledge and demonstrative knowledge. Intuitive knowledge is knowledge that is self-evident, such as the mathematical truths that are immediately apparent to us. Demonstrative knowledge is knowledge that is derived through reasoning and evidence, such as scientific or historical knowledge.

Locke also distinguishes between primary and secondary qualities of objects. Primary qualities are those that are inherent in the object itself, such as shape, size, and motion. Secondary qualities are those that are perceived by the observer, such as color, taste, and smell. Locke argues that our perception of secondary qualities is not a direct perception of the object itself, but rather a product of our own sensory experience.

The Essay Concerning Human Understanding also addresses the limits of human knowledge. Locke argues that our knowledge is limited by the extent of our experience, and that there are many things that we cannot know with certainty. He acknowledges the existence of a realm of uncertainty and ambiguity, which he calls the realm of opinion. In this realm, we must rely on probability and judgment rather than certainty.

One of the most important aspects of the Essay Concerning Human Understanding is Locke’s theory of language. He argues that language is essential to human thought and knowledge, and that words are the vehicles by which we convey our ideas and communicate with one another. Locke contends that words are not simply arbitrary symbols, but rather are connected to the ideas and experiences that they represent.

Locke’s theory of language also includes a critique of the use of language in philosophical discourse. He argues that many philosophical debates are based on the misuse of language, and that many of the disputes between philosophers are the result of different uses of the same words. He advocates for a more precise and rigorous use of language in philosophical discourse, and argues that this would lead to greater clarity and understanding.

The Essay Concerning Human Understanding has had a profound impact on the development of modern philosophy, particularly in the areas of epistemology and metaphysics. Locke’s rejection of innate ideas and his emphasis on the role of experience and reason in human knowledge have been influential in shaping modern empiricism and rationalism.

Locke’s work has also had an impact on political philosophy. He argues that all individuals are entitled to certain natural rights, including the right to life, liberty, and property. These ideas were influential in the development of the concept of natural rights and the modern theory of liberal democracy.

In conclusion, An Essay Concerning Human Understanding is a monumental work of philosophy that presents a comprehensive account of human knowledge and understanding. Locke’s rejection of innate ideas and his emphasis on the role of experience and reason in human cognition have had a profound impact on modern philosophy and have helped to shape our understanding of the nature and limits of human knowledge. The Essay Concerning Human Understanding is a must-read for anyone interested in philosophy, epistemology, and the nature of human thought and understanding.

John Stuart Mill’s On Liberty: Key Concept

On Liberty, written by the philosopher and economist John Stuart Mill, was published in 1859. The book is a philosophical defense of individual liberty, arguing that people should have the freedom to think, speak, and act as they wish, as long as they do not harm others. The work is considered a classic of political philosophy and has had a profound influence on modern liberal thought.

Mill begins the book by stating that the main issue in society is the struggle between individual liberty and social control. He argues that the ultimate goal of society should be the development of human happiness and individuality, and that this can only be achieved by allowing people to pursue their own interests and express their own opinions. He contends that the suppression of individuality, both in thought and action, is a threat to progress and a hindrance to the development of society.

One of the central themes of On Liberty is the concept of the “harm principle.” Mill argues that the only justification for limiting individual freedom is to prevent harm to others. He defines harm as any action that infringes on the rights of others or causes them harm, and contends that any interference with individual liberty must be based on this principle. According to Mill, the government should only intervene when an individual’s actions are likely to cause harm to others, and should otherwise leave people free to pursue their own interests.

Mill also defends the concept of freedom of speech, arguing that the exchange of ideas is necessary for the development of knowledge and understanding. He contends that even unpopular or controversial opinions should be allowed to be expressed, as long as they do not directly harm others. Mill believes that the free exchange of ideas is essential to a healthy society and that censorship is a form of tyranny that stifles creativity and innovation.

In addition to defending individual liberty, Mill also addresses the role of government in society. He argues that the government should have a limited role, with its main function being to protect individuals from harm and to provide public goods such as infrastructure and education. He contends that the government should not interfere in the private lives of individuals, and that people should be free to make their own choices about their own lives.

Mill’s work has had a profound influence on liberal thought, and his ideas continue to be relevant today. His defense of individual liberty and freedom of speech have been used to argue for the decriminalization of homosexuality, the legalization of drugs, and the protection of free speech online. Mill’s work is a reminder of the importance of individual freedom and the need to protect it from undue interference by the state or other individuals.

In conclusion, On Liberty is a seminal work in the field of political philosophy, and its arguments for individual liberty and freedom of speech continue to be influential today. Mill’s work is a reminder of the importance of protecting individual liberty from undue interference, and of the role that government should play in protecting individuals from harm and promoting the public good. On Liberty is a must-read for anyone interested in political philosophy or the nature of individual freedom in modern society.

Principles of Political Economy: Key Concepts

Principles of Political Economy is a book written by John Stuart Mill in 1848, which is considered one of the most influential works on economics and political philosophy. In this book, Mill explores the ideas of classical economics and the role of the state in economic affairs. This summary will provide an overview of the key concepts presented in the book.

Mill’s main thesis in “Principles of Political Economy” is that economics is a science, and that it should be studied as such. He argues that economics is not just concerned with the accumulation of wealth, but also with the distribution of wealth and the well-being of society as a whole.

One of the key concepts that Mill discusses in the book is the idea of the division of labor. He argues that the division of labor is necessary for economic growth, but that it can also lead to social and economic inequality. Mill suggests that the state has a role to play in ensuring that the benefits of economic growth are distributed fairly.

Another important concept that Mill discusses is the idea of utility. He argues that individuals seek to maximize their own utility, or happiness, and that this is the driving force behind economic activity. Mill suggests that the state can promote the general welfare of society by ensuring that markets are free and competitive, and by regulating economic activity to prevent abuses of power.

Mill also discusses the concept of free trade in “Principles of Political Economy”. He argues that free trade is beneficial for all nations, as it allows for the efficient allocation of resources and promotes economic growth. Mill suggests that the state should not interfere with free trade unless it is necessary to protect the general welfare of society.

In addition to these concepts, Mill also discusses the role of government in the economy. He argues that the state should be involved in economic affairs to promote the general welfare of society, but that it should also be limited in its powers. Mill suggests that the state should provide public goods, such as education and infrastructure, but that it should not interfere with the workings of the market unless it is necessary to protect the general welfare of society.

Overall, “Principles of Political Economy” is an important work that explores the ideas of classical economics and the role of the state in economic affairs. Mill’s ideas have had a profound influence on modern economics and political philosophy, and his work continues to be studied and debated today.

Discipline and Punish Summary

Discipline and Punish: The Birth of the Prison is a book written by French philosopher Michel Foucault. The book was published in 1975 and is considered one of the most influential works of the 20th century. The book traces the evolution of Western penal systems, from the public spectacle of torture and execution to the hidden, bureaucratic systems of punishment and surveillance that emerged in the 18th and 19th centuries.

Foucault’s central argument is that modern penal systems are based on the logic of discipline, rather than punishment. While traditional forms of punishment were primarily concerned with inflicting pain and retribution, the modern prison system aims to produce obedient, productive citizens through the constant surveillance and control of their bodies and minds.

Foucault begins the book by describing the gruesome public punishments that were common in pre-modern Europe. These punishments were designed to terrorize the public and reinforce the power of the ruling class. However, Foucault argues that these forms of punishment were gradually replaced by more humane, but no less oppressive, systems of control.

Foucault traces the development of the modern prison system to the 18th century, when European societies underwent a transformation from feudalism to capitalism. As the power of the ruling class began to wane, new forms of social control were needed to maintain order and discipline. The prison emerged as a way of punishing criminals while also providing a means of social control.

Foucault argues that the prison system operates through a series of techniques that are designed to break down the individual’s sense of self and to produce obedience and conformity. These techniques include constant surveillance, isolation, and the regulation of every aspect of the prisoner’s life. The prison system seeks to create a docile, obedient workforce that is willing to submit to the demands of the capitalist system.

Foucault also argues that the prison system is part of a broader system of social control that includes schools, hospitals, and other institutions. These institutions are all designed to produce obedient, productive citizens who are willing to accept their place in society and to conform to its norms and values.

Throughout the book, Foucault emphasizes the role of power in shaping social institutions and practices. He argues that power is not something that is possessed by individuals or groups, but rather something that is distributed throughout society. Power is exercised through a series of techniques and practices that are designed to maintain the status quo and to reinforce existing power relations.

One of the key themes of Discipline and Punish is the idea of “panopticism.” Foucault uses the term to describe a form of social control that operates through constant surveillance. The panopticon was a prison design that was first proposed by the philosopher Jeremy Bentham in the late 18th century. The panopticon was a circular prison with a central watchtower that allowed guards to observe the prisoners at all times without the prisoners knowing whether they were being watched or not. Foucault argues that the panopticon represents the ideal form of social control, in which the individual is constantly under surveillance and therefore constantly disciplined.

Foucault’s analysis of the prison system has been highly influential in the fields of sociology, criminology, and cultural studies. His work has inspired a generation of scholars to examine the role of power and control in shaping social institutions and practices.

In conclusion, Discipline and Punish is a powerful critique of the modern prison system and the broader system of social control that it represents. Foucault argues that the prison system is not primarily concerned with punishment, but rather with the production of obedient, productive citizens who are willing to submit to the demands of the capitalist system.

The Montessori Theory: Key Concepts

Maria Montessori was an Italian physician and educator who developed a unique approach to early childhood education known as the Montessori method. Her approach is grounded in the belief that children are naturally curious and possess an innate desire to learn. Montessori’s theory is based on the idea that children learn best through exploration, self-discovery, and hands-on experiences.

The Montessori Method

The Montessori method is a child-centered educational approach that emphasizes freedom within limits. Children are encouraged to explore their environment and learn through self-directed activities, while the teacher serves as a facilitator, guiding the child’s learning rather than dictating it.

The Montessori classroom is carefully designed to foster independence, self-discipline, and a sense of order. Children are free to move about the classroom and choose their own activities, which are typically arranged on low shelves to make them easily accessible. The activities are designed to be self-correcting, so that children can learn from their mistakes and develop problem-solving skills.

Montessori Materials

Central to the Montessori method are the specially designed materials that are used to facilitate learning. Montessori materials are typically made from natural materials such as wood, metal, and fabric. They are designed to be aesthetically pleasing and to appeal to the senses, with bright colors, varied textures, and interesting shapes.

The materials are arranged in a specific sequence, with each activity building on the skills learned in the previous one. For example, a child might start with a set of wooden blocks and progress to a set of colored beads, which can be used to learn math concepts such as addition and subtraction.

The Role of the Teacher

In the Montessori method, the teacher plays a crucial role in guiding the child’s learning. Rather than lecturing or directing the child’s activities, the teacher observes the child and provides guidance and support as needed. In this approach, the role of the teacher is crucial, as they play a critical role in creating a nurturing environment that fosters independence, creativity, and curiosity.

In the Montessori classroom, the teacher is often referred to as a guide or facilitator. They observe the children’s interests, needs, and abilities and use that information to create an individualized learning plan for each child. The teacher’s primary responsibility is to create an environment that is conducive to learning, where children can feel safe and free to explore and discover.

One of the essential roles of the teacher in the Montessori method is to provide guidance and support to children as they navigate their learning journey. The teacher helps children to develop their self-confidence and independence by providing the necessary tools and resources they need to explore their interests and passions.

The teacher is also responsible for creating a classroom culture that encourages collaboration and respect. In the Montessori classroom, children are encouraged to work together and learn from each other. The teacher facilitates this by creating opportunities for group work and ensuring that each child has an equal opportunity to participate.

Another crucial role of the Montessori teacher is to model positive behavior and attitudes. Children learn by observing the adults around them, and the teacher sets the tone for the classroom. The teacher demonstrates respect, kindness, and patience, which helps children to develop these qualities themselves.

In conclusion, the role of the teacher in the Montessori method is critical. They create a safe and nurturing environment that encourages children to explore, discover, and learn. The teacher provides guidance, support, and resources that help children develop their self-confidence and independence. They model positive behavior and attitudes and create a culture of collaboration and respect. By playing these roles, the teacher helps children to develop into confident, creative, and curious learners.

The Purpose of Man According to St. Thomas Aquinas

Saint Thomas Aquinas was a theologian, philosopher, and writer who lived during the 13th century. He is considered one of the most influential thinkers in the history of Western philosophy and is famous for his Summa Theologica, a comprehensive work on theology and philosophy. According to Aquinas, the purpose of man is to seek happiness, which is the ultimate end of human existence. In this essay, we will explore Aquinas’s views on the purpose of man in detail.

The Nature of Man

According to Aquinas, man is a rational being, endowed with intellect and free will. He is created in the image of God and has the capacity to know and love Him. Man’s rational nature allows him to reason and understand the world around him, and his free will enables him to choose between good and evil. In Aquinas’s view, man’s nature is intrinsically good, but he is also prone to sin due to the effects of original sin.

The End of Man

Aquinas believed that the end or purpose of man is to seek happiness. However, he did not define happiness in the conventional sense of pleasure or satisfaction. Instead, he viewed happiness as the ultimate goal of human existence, which could only be achieved through a life of virtue and the attainment of the beatific vision, or the direct vision of God.

Aquinas believed that happiness was not something that could be achieved by external means such as wealth or power, but rather by internal means such as wisdom, self-control, and moral virtue. He argued that human beings are naturally inclined to seek happiness and that this inclination is part of their rational nature.

Virtue and Happiness

According to Aquinas, virtue is the key to happiness. Virtue is a habit or disposition of the soul that enables a person to act in accordance with reason and the moral law. Virtue is acquired through practice and habituation and is expressed in actions that are morally good and beneficial to oneself and others.

Aquinas identified four cardinal virtues: prudence, justice, temperance, and fortitude. Prudence is the ability to make wise decisions and judgments, justice is the ability to treat others fairly and equitably, temperance is the ability to control one’s desires and passions, and fortitude is the ability to face adversity and overcome fear.

In addition to the cardinal virtues, Aquinas believed that there are three theological virtues that are essential for the Christian life: faith, hope, and charity.

Faith is the first theological virtue, and it is the foundation of all Christian belief. According to Aquinas, faith is a supernatural gift from God that enables us to believe in Him and accept the truths of the Christian faith. Faith is not based on our own reasoning or intellect but is a free gift from God that we receive through grace. Faith involves both intellectual assent to the truths of Christianity and a personal trust in God. Through faith, we believe in God’s existence, His revelation to us through Scripture and Tradition, and the doctrines of the Church.

The second theological virtue is hope, which is closely related to faith. While faith involves believing in God’s promises, hope involves trusting in them. Aquinas describes hope as the “sure and steadfast expectation of eternal life and the grace to attain it.” Hope is a gift from God that enables us to trust in His promises, even when we face difficulties and challenges in life. It is through hope that we can endure suffering and persevere in our Christian journey, trusting that God will ultimately bring us to eternal life.

The third and final theological virtue is charity, which Aquinas describes as the greatest of all virtues. Charity is the supernatural love of God that is poured into our hearts through the Holy Spirit. It is through charity that we love God above all things and love our neighbors as ourselves. Charity is not merely a feeling or emotion but is a decision of the will to seek the good of others for their own sake. It is through charity that we imitate Christ, who loved us and gave Himself up for us.

Rousseau’s Social Contract Theory: Key Concepts

Jean-Jacques Rousseau’s Social Contract Theory is a political philosophy that advocates for the establishment of a civil society based on the principles of liberty, equality, and fraternity. According to Rousseau, the social contract is an agreement between individuals to form a government that will protect their natural rights and promote the common good. In this essay, we will explore Rousseau’s Social Contract Theory in detail.

The State of Nature

According to Rousseau, the state of nature is a hypothetical scenario in which human beings lived before the creation of civil society. In this state, individuals were free and equal, and they possessed natural rights such as life, liberty, and property. However, the state of nature was also a state of war, as individuals had to compete with each other for resources and survival. The absence of government meant that there was no law and order, and individuals had to rely on their own strength and cunning to protect themselves.

The Social Contract

To escape the state of nature and establish civil society, Rousseau proposed the social contract. The social contract is an agreement between individuals to form a government that will protect their natural rights and promote the common good. In exchange for protection and other benefits provided by the government, individuals surrender some of their natural rights and freedoms to the community as a whole. This way, the government can regulate society, prevent conflicts, and ensure that everyone is treated fairly.

Rousseau’s concept of the social contract is different from the traditional theory of the contract, which assumes that individuals voluntarily enter into the agreement to protect their self-interest. According to Rousseau, the social contract is a moral and political obligation that arises from the common good. The individuals who agree to the social contract are not acting out of self-interest but rather out of a sense of duty to the community as a whole.

The General Will

The cornerstone of Rousseau’s Social Contract Theory is the concept of the general will. The general will is the collective will of the people, and it represents the common good. The general will is different from the individual wills of the members of society, as it takes into account the interests of everyone, not just a select few. The general will is not a simple majority rule, as it is not just the sum of individual preferences. Rather, it is an expression of the shared values and beliefs of the community.

Rousseau believed that the government should be based on the general will. The government is not an entity that stands above the people, but rather an expression of the people’s collective will. The government should represent the common good, and its primary function is to enforce the general will. The government should also ensure that everyone is treated fairly and that there is no discrimination or exploitation.

The Sovereign

The sovereign is the entity that embodies the general will, and it is the source of political power. The sovereign can be either a single individual or a group of individuals, but it represents the entire community. The sovereign is the ultimate authority in civil society, and all other political institutions derive their legitimacy from it.

Rousseau believed that the sovereign should be an active participant in the political process. The sovereign should not simply delegate power to the government but should also play an active role in decision-making. This way, the government remains accountable to the people, and the general will is always expressed.

Criticism of Rousseau’s Social Contract Theory

Rousseau’s Social Contract Theory has been subject to a lot of criticism over the years. One of the main criticisms is that the theory is based on an unrealistic and romanticized view of the state of nature. In reality, the state of nature was likely to be a violent and chaotic place, where life was short and brutal.

What is Independent Variable?

The concept of independent variable is an essential aspect of scientific research and experimentation. It is a variable that is manipulated or changed by the researcher to observe its effect on the dependent variable. The dependent variable is the variable that is affected by changes in the independent variable, and it is the outcome of the experiment. In this context, the independent variable is often referred to as the predictor variable, while the dependent variable is referred to as the response variable.

To understand the meaning of independent variable better, it is necessary to consider some examples. Suppose a researcher wants to investigate the relationship between caffeine consumption and alertness. The independent variable in this scenario would be the amount of caffeine consumed, while the dependent variable would be the level of alertness. The researcher can manipulate the independent variable (caffeine consumption) by giving different doses of caffeine to the participants and observing their level of alertness, which is the dependent variable.

Another example could be a study that investigates the effect of exercise on weight loss. In this scenario, the independent variable would be the level of exercise, and the dependent variable would be the amount of weight lost. The researcher can manipulate the independent variable (level of exercise) by assigning participants to different exercise regimes and observing the amount of weight they lose, which is the dependent variable.

The key characteristic of an independent variable is that it must be manipulated or controlled by the researcher. In contrast, the dependent variable is observed and measured without any interference or manipulation by the researcher. This distinction is essential because it allows researchers to establish cause-and-effect relationships between the independent and dependent variables.

In scientific research, it is crucial to have a clear understanding of the independent variable because it allows researchers to design experiments that can isolate the effects of the independent variable on the dependent variable. This approach is critical because it enables researchers to draw valid conclusions about the relationship between the two variables. If the independent variable is not controlled or manipulated, it becomes difficult to establish a causal relationship between the independent and dependent variables.
