Philosophy is the study of fundamental questions concerning the nature of what is and what ought to be. The basis of the study of philosophy is the ancient search for self-knowledge and the love of wisdom. In Plato's Dialogues, Socrates says, "wonder is the feeling of philosophy, and philosophy begins in wonder."
The study of philosophy employs the human capacity to reflect, reason, and make critical judgments in response to such questions as: What is the good? What is justice? What is the nature of reality? What, if anything, can we know for certain? What is the nature of beauty? What are human beings essentially? What is the meaning of life? Philosophy also examines the principles of logical, scientific, and religious thought, and the great rational systems developed by philosophers in their search for truth.
