However, it is this kind of knowledge that provides a temporary foundation for the value and practice of many of us in daily life, making them feel worthwhile. Rationality and theoretical knowledge are acquired through special study. We can acquire this systematic and theoretical humanistic knowledge by studying history, philosophy, art, religion, literature and science.
