According to Socrates, as Plato reports, “Wonder is the only beginning of philosophy.” Later, Aristotle, in response to his predecessors, especially the Ionian philosophers, said that “It is owing to their wonder that men both now begin and at first began to philosophize.” (See John Llewelyn, “On the saying that philosophy begins in thaumazein,” Afterall: A Journal of Art, Context and Enquiry, Issu3 4 (2001), pp. 48-57. https://www.jstor.org/stable/20711438?seq=1#page_scan_tab_contents.
This is precisely the context and basis of the now famous claim that philosophy begins in wonder.
But what kind of wonder is this? For sure, wonder includes the feeling of surprise coupled with admiration, that is, when one is being curious or being in awe. But this is not enough. Wonder as the beginning of philosophy is precisely “philosophic wonder,” that is, the feeling of being perplexed. For example, the ancient Greek philosophers were perplexed about the origin and nature of the world. As Aristotle writes:
“For men were first led to study philosophy, as indeed they are today, by wonder. Now, he who is perplexed and wonders believes himself to be ignorant…they took to philosophy to escape ignorance…(Aristotle, Metaphysics 982b, tr. A.E. Taylor).”
In this sense, philosophic wonder seeks clarity by trying to understand the perplexities or vagueness or confusion that shrouded the inquiring mind. In other words, philosophic wonder seeks answers to or at least make sense of the mysterious world. Thus, when one begins to make sense of the questions regarding, for example, the origin of the world, or the meaning and purpose of life, one begins to philosophize. Thus, in philosophic wonder, one is not merely amazed by the mysteriousness of the world or of life, but seeks to understand this mystery. In a word: one thinks!
Given the above brief discussion on the origin of philosophy on the conceptual level, it is therefore reasonable to suppose that Western philosophy originated in Miletus, because Thales, the acclaimed first philosopher in the Western world, was from Miletus. Miletus during the time of Thales was the richest and the most powerful of all the Ionian cities, and was the first center of scholarship in ancient Greece. Ionia was a Greek city- state on the coast of Asia Minor, now Turkey.
It is worth noting that with the decline of Ionia, which began with its conquest by the Persians in 546 BCE, the intellectual life of Greece moved to Croton in southern Italy in 530 BCE. Croton was a splendid and powerful city-state of Greece to where Pythagoras emigrated from Samos and founded the Pythagorean Brotherhood [See Arthur Hilang Armstrong, An Introduction to Ancient Philosophy (London: Little Adams Quality Paperbacks, 1989), p. 5].
However, if philosophy begins in wonder, how do we exactly know that Thales was the first philosopher, that he was the first one to wonder, that is, the first one to attempt to make sense of the mysteriousness of the world? In fact, we cannot deny the occurrence of other pre-philosophical rumblings in Egyptian and Babylonian cultures, as well as in India and China. For sure, there were great thinkers that existed in each of these cultures, and there are evidence that some of the earliest Greek philosophers had come in contact with at least some of the products of Egyptian and Babylonia thought. And, of course, we cannot absolutely determine the first person who wondered or philosophized. But it is commonly believed that Thales was the first philosopher because he was the first, at least in recorded history, to put his philosophy into writing. In fact, we find in Thales, and many philosophers after him, some reasoned arguments for the origin and development of the world. Indeed, this is a unique feature of ancient Greek philosophy that distinguishes it from the pre-philosophical rumblings of other cultures.
To reiterate, Western philosophy begins in wonder, and that the origin of philosophy in terms of place is said to be in Miletus, Ionia.
In these notes, I will briefly sketch the definition of philosophy, its origin, and its major branches. Specifically, it will address the question: What is Philosophy?
Meaning of Philosophy
Philosophy, particularly Western philosophy, comes from the two Greek words philia, which means “love” and sophia, “wisdom”. Thus, etymologically speaking, philosophy means the love of wisdom.
As is well known, love in this context is understood as a strong desire for a particular object; while wisdom is understood as a correct application of knowledge. Thus, philosophy as the love of wisdom, at least in this context, could refer to the strong desire of the human person to possess knowledge and apply it correctly. It’s not a coincidence, therefore, that most philosophers in the Ancient World, particularly in Greece, India, and China were sages or wise men. Think for example of Socrates, Gautama Buddha, Confucius, and Lao Tzu.
Traditionally, however, philosophy is defined as a science that studies beings in their ultimate causes, reasons, and principles through the aid of human reason alone. And when we speak of “being” or “beings” in philosophy in this context, we mean all things that exist, material or immaterial. An example of beings are “stones”, “trees”,
“persons”, “cars”, air, water; and the notions of “God”, “soul”, “spirit”. All of these are beings, and philosophy studies their ultimate causes, reason, and principles through the aid of reason alone.
In other words, philosophy is concerned with the reason and principles that account for everything that exists. Thus, some of the basic questions in philosophy are:
What is the origin of the world, of everything that exists?
Why do these things exist, rather than not exist at all?
Is there God? If so, how can we justify the goodness of God in the face of evil?
What is the meaning and purpose of life? Why do we have to suffer?
If one is suffering from an unbearable pain, such as cancer, is it morally right to resort to euthanasia or assisted suicide?
These are just some of the questions that philosophy attempted to address. And in doing so, philosophy uses reason as a tool, which can be expressed in many forms, such as the ability to reflect, question, articulate one’s thought, and analyze certain phenomenon or event. In short, philosophy attempts to understand things in a critical and logical manner.
It is important to note, however, that philosophers do not agree on a single definition of philosophy. In fact, philosophers differ in their basic understanding of philosophy. For example, Karl Jaspers, a famous German existential philosopher, understands philosophy as a discipline in which questions are more important than answers because answers themselves will, in turn, become questions.
Major Branches of Philosophy
After addressing the question “what is philosophy?”, let us now discuss the major branches of philosophy. Philosophy is normally divided into four major branches, namely: Metaphysics, Epistemology, Logic, and Ethics.
Metaphysics comes from the two Greek words meta, which means “beyond” or “after” and physika, “physical” or “nature”. Hence, etymologically speaking, metaphysics means the study of things beyond the physical, that is, concepts or things that cannot be experienced, such as the concepts of God, freedom, and soul.
Metaphysics is commonly understood as the foundation of philosophy. In fact, Aristotle calls it the “first philosophy”. Originally, the Greek word metaphysika, which literally means “after physics”, actually designated that part of Aristotle’s works, which came after those chapters that dealt with physics. However, it was misappropriated later by the Medieval commentators on classical texts as that which is beyond the physical. Thus, over time, metaphysics has been understood as the study of that which exists beyond the physical.
Metaphysics is subdivided into two, namely, General Metaphysics and Special Metaphysics. General Metaphysics is also referred to as Ontology. Under Special Metaphysics, we have Cosmology, Psychology or Anthropology, and Natural Theology or Theodicy.
Ontology is derived from the two Greek words onto, which means “being” or “that which is”, that is, everything that exists; and logos, which means “knowledge” or
“study”. (Note, however, that the term logos in ancient Greek scholarship have different connotations. For example, Heraclitus, a Greek philosopher of the late 6th century BCE, understands Logos as reason or the underlying principle of all that is.) Ontology, therefore, is the specific branch of philosophy that studies beings in their ultimate causes, reasons, and principles through the aid of reason alone. In other words, Ontology studies the first principles or the essence of all things.
Some of the basic questions in ontology are:
What is being?
Why do things exist, rather than not exist at all?
What is the meaning and nature of reality?
What is the underlying principle of all that exist?
Is there nothing?
Please note that my concern here is just to describe very schematically the four major branches of philosophy. If you want to know more about the nature and dynamics of Ontology per se, see John Rickaby, S.J. General Metaphysics. https://www3.nd.edu/~maritain/jmc/etext/gm.htm.
Cosmology, from the Ancient Greek words kosmos, which means the “world” and logos, meaning “study”, is the specific sub-branch of philosophy that studies the world (or universe), including its origin, dynamics, and characteristics, as well as the laws that govern its order.
Some of the basic questions in cosmology are:
What is the origin of the world?
What is the basic material of which the world is formed?
How do things arise?
In what consists its (the world) fundamental form or principle of order?
Is the world or universe infinite?
Psychology comes from the two Greek words psyche, which means “soul” (but loosely understood as mind) and logos, study. Thus, psychology is the specific sub-branch of philosophy that studies the soul or mind. Broadly construed, though, psychology is the study of the nature and dynamics of the human person as a whole, with emphasis on the way the person’s mind functions and the way she behaves.
Some of the questions in psychology are:
What is the nature of the human person?
Is there such thing as human nature?
What is the meaning and purpose, if any, of life?
Is there life after death?
How do we account for the existence of sufferings in the world?
Theodicy (Natural theology) is derived from the Greek word theos, which means God. The word theodicy was coined by the famous 18th century German philosopher Gottfried Wilhelm Leibniz in his 1710 work titled Théodicée. Broadly construed, theodicy is the study of God. But specifically, theodicy is concerned with the justification of the goodness of God in the face of the existence of evil in the world.
Some of the questions in theodicy are:
Is there God?
What and who is God, if He exists at all?
How do we prove the existence of God?
If God exists, how do we justify the existence of evil and suffering in the world?
Does a belief in God really necessary?
For a detailed discussion on special metaphysics, see Louis de Poissy, Special Metaphysics. https://maritain.nd.edu/jmc/etext/cp27.htm.
The second major branch of philosophy is Epistemology.
Epistemology comes from the two Greek words episteme, which means knowledge, and logos which means study. It is formally defined as the study of the nature and scope of knowledge and justified belief. Specifically, it analyzes the nature of knowledge and how it relates to similar notions, such as truth, belief, and justification.
The third major branch of philosophy is Logic. Logic comes from the Greek word logos, which, as I already mentioned, has different meanings. It is defined as the science of correct thinking or the study of the principles and criteria of a valid argument. More specifically, logic attempts to distinguish sound or good reasoning from unsound or bad reasoning.
Some of the basic questions in logic are:
What is correct reasoning?
What distinguishes a good argument from a bad one?
How can we detect a fallacy in an argument?
What are the criteria for determining the validity of an argument?
What are the types of logic?
Ethics is derived from the Greek word ethos, which originally means custom or habit. Broadly construed, ethics is the morality of human actions. Ethics, therefore, is concerned with questions of how human persons ought to act, and the search for a definition of a right conduct and the good life.
It is important to note that ethics is not the same with morality. This is because ethics denotes the theory of right action and the greater good, while morality indicates practice, that is, the rightness or wrongness of a human action.
Some of the questions in ethics are:
What is a right conduct as that which causes the realization of the greatest good?
How do we determine a right conduct? In other words, what makes a right conduct right?
What is a good life and can we attain it?
What is the difference between human act and actions that are based on instinct?
What do people think is right?
It is important to note that some scholars argue that there are five major branches of philosophy, namely, metaphysics, epistemology, ethics, logic, and aesthetics. While there is nothing wrong with this contention, in these notes, I adhered to the classical understanding of the major branches of philosophy, namely, metaphysics, epistemology, ethics, and logic. The argument is that “aesthetics”, which is the study of beauty, is under metaphysics.
It is also important to note that some scholars put ethics and aesthetics under axiology, the philosophical study of value. There is also nothing wrong with it. It’s just that, as intimated above, I adhered to the classical understanding of the major branches of philosophy, namely, metaphysics, epistemology, ethics, and logic.
As we can see, there is no absolute, one-size-fits-all understanding of the major branches of philosophy. Hence, our understanding of the major branches of philosophy depends entirely on a specific tradition one is coming from.
