What is Philosophy?
The term “philosophy” comes from the two Greek words “philos” (φίλος) which means lover and “sophia” (σοφία) which means wisdom. Etymologically speaking, philosophy means “love of wisdom.”
It must be noted that love here (philos) is different from the other kinds of love the Greeks distinguished, namely eros and agape. Love in philosophy must be understood as a strong desire for a particular object, while wisdom as the knowledge of the ultimate causes and principles. Philosophy as the love of wisdom, therefore, refers to the strong desire of the human person to possess the definitive answers to life’s deepest questions. It is no coincidence then that most philosophers in the ancient world, such as Socrates, Buddha and Confucius, were wise men.
Philosophy: A General Definition
Traditionally, philosophy is defined as the science that studies beings in their ultimate causes, reasons, and principles through the aid of human reason alone. Here, when we speak of being or beings, we mean all things that exist, both material or immaterial. Examples of beings are trees, animals, persons, books, God, etc. Practically, everything that exists is a being, and philosophy studies the definitive reasons and explanations to the deep questions that may arise from them.
Some basic questions that philosophy tries to answer are:
- What is the origin of the world?
- Why do we exist rather than not exist at all?
- Does God exist? If so, how can we justify his goodness in the presence of evil?
- What is the meaning and purpose of life? Of suffering?
- What is true knowledge? What are the limits of human knowledge?
- If one is suffering from an unbearable pain such as cancer, is it morally right to resort to euthanasia?
Philosophy tries to answer these questions through the use of human reason alone; that is, it does so critically and logically, using reflection, analysis, other questions and arguments, and without resorting to customary, mythological, or religious answers.
It is important to note, however, that not all philosophers agree on a single definition of philosophy. In fact, they differ in their basic understanding of it. Karl Jaspers, for example, 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.
