St. Thomas Aquinas’s Ethics

Aquinas’s ethics is based on his philosophical and theological understanding of human nature, God, and the universe. According to Aquinas, ethics is a branch of philosophy that is concerned with how human beings can achieve happiness and live a good life. For Aquinas, the ultimate goal of human life is union with God, and ethical behavior is essential for achieving this goal. In this essay, we will explore Aquinas’s ethics, including his understanding of natural law, virtues, and moral reasoning.

Aquinas’s ethics is grounded in his understanding of human nature, which he believes is composed of two parts: the rational and the animal. The rational part of human nature is characterized by the ability to reason, while the animal part is characterized by the desire for pleasure and the avoidance of pain. For Aquinas, human beings are meant to use their rational faculties to guide their actions and control their desires, which are often driven by the animal part of their nature.

Aquinas’s understanding of ethics is also grounded in his understanding of God and the universe. He believes that God is the ultimate source of all goodness and that human beings are created in God’s image. As a result, human beings have a natural inclination towards goodness and are capable of moral reasoning. Furthermore, Aquinas believes that the universe is ordered and that human beings can understand this order through reason.

One of the key concepts in Aquinas’s ethics is natural law. According to Aquinas, natural law is the moral law that is inherent in the nature of things. It is the order and purpose that is built into the universe by God, and human beings can discover it through reason. Natural law is based on the principle that human beings should pursue the good and avoid evil, which is the same as saying that they should act in accordance with their nature.

For Aquinas, natural law is not a set of rules that are imposed on human beings from the outside, but rather a set of principles that are discovered through reason. Natural law is not subjective, but rather objective, and applies to all human beings regardless of their culture or religion. Natural law provides a framework for moral reasoning and decision-making, and it is through natural law that human beings can discern what is right and wrong.

Another key concept in Aquinas’s ethics is virtue. According to Aquinas, virtues are habits or dispositions that enable human beings to act in accordance with natural law. Virtues are acquired through practice and habituation, and they enable human beings to develop the capacity to act in accordance with reason and to control their desires. Virtues are also essential for achieving the ultimate goal of human life, which is union with God.

Aquinas identifies two types of virtues: theological virtues and cardinal virtues. Theological virtues are faith, hope, and charity, which are infused into the human soul by God and enable human beings to participate in the divine life. Cardinal virtues are prudence, justice, fortitude, and temperance, which are acquired through practice and habituation and enable human beings to live a good life in accordance with natural law.

Prudence is the virtue of practical wisdom, which enables human beings to make good decisions and to act in accordance with natural law. Justice is the virtue of fairness and involves giving each person what they are due. Fortitude is the virtue of courage and involves facing difficulties and adversity with strength and perseverance. Temperance is the virtue of self-control and involves moderating one’s desires in accordance with reason.

Aquinas’s ethics is also grounded in his understanding of moral reasoning. According to Aquinas, moral reasoning is a process of practical reasoning that involves discerning what actions are in accordance with natural law and what actions are not.

Aquinas believed that moral reasoning is essential for living a good life and for achieving the ultimate end of happiness. He believed that moral reasoning is grounded in reason and in the natural law, which is an objective moral law that is based on human nature.

Aquinas saw reason as the key to moral decision-making, and he believed that reason can lead us to a knowledge of the natural law. He believed that the natural law is based on the primary precept of self-preservation, which is the instinct to survive and thrive. From this primary precept, secondary precepts are derived, which are specific moral guidelines for how to achieve self-preservation, such as the prohibition against murder, theft, and adultery.

Aquinas believed that moral reasoning involves the application of reason to the natural law in order to determine the right course of action. He believed that moral reasoning involves both deductive and inductive reasoning. Deductive reasoning involves starting with general principles and applying them to specific cases. Inductive reasoning involves starting with specific cases and drawing general principles from them.

Aquinas believed that moral reasoning involves a process of discernment, which involves considering various factors and determining the best course of action based on the natural law and the virtues. He believed that moral reasoning involves not just the intellect, but also the will, which involves the ability to choose the right course of action.

Aquinas believed that moral reasoning involves both practical reason and speculative reason. Practical reason involves determining the right course of action in specific situations, while speculative reason involves the contemplation of abstract principles and concepts. He believed that practical reason is essential for living a good life, but that speculative reason is also important for understanding the nature of morality and for contemplating the ultimate end of happiness.

Aquinas believed that moral reasoning is not just an individual endeavor, but that it also involves the community and the tradition of moral reasoning that has developed over time. He believed that the community provides guidance and support for moral decision-making, and that the tradition of moral reasoning provides a framework for understanding the natural law and the virtues.

Aquinas believed that moral reasoning involves a process of growth and development, and that it requires practice and habituation. He believed that the virtues are the key to developing moral reasoning skills, and that they are developed through habit and practice. He believed that the moral virtues are necessary for achieving the ultimate end of happiness and for living a good life.

Aquinas believed that moral reasoning involves a balance between reason and emotion, and that emotions can either help or hinder moral decision-making. He believed that emotions can provide motivation for moral action, but that they can also lead us astray if they are not properly regulated by reason.
