This document provides an overview of philosophy, including its definition, goals, and scope. Philosophy is defined as the systematic study of the foundations of human knowledge and seeking answers to ultimate questions. The main goals of philosophy are wisdom, truth, values, and examining social relationships. Its scope includes the nature of the universe, justice, knowledge, reason, beauty, and language. Idealism emphasizes the mind/spirit and holds that reality consists only of ideas, rejecting objects' independence from the mind. In contrast, realism represents things accurately and holds that objects exist independently outside the mind, regardless of human perception.
