Quest: I Think Therefore I Am

Life is replete with endless questions with no easy answer. Pondering on them creates apparent progress in our search for truth. However, we are not alone in this endeavor. Thoughtful philosophers from all around the world have reflected, discussed and written down their meditations for further contemplation. It is an arduous journey that may be filled with existential dread. But, the mind's endless curiosity yearns for answers.

Add philosophy books you've read and that deepened your understanding of our existence and the meaning of life.
