3.1 The history of philosophy is full of minor and majorphilosophers who have used deductive logic to address the toughperennial questions of life related to metaphysics (what is real)epistemology (what is true) and ethics (what is the good life).Some of the issues they have responded to have been quite esotericsuch as where or how the human brain connects with the mind andthinking process (Plato & Descartes). Many of the earlyphilosophers tried to explain how life changes but also maintainssome continuity (Pythagoras & Socrates). Others wrestled withthe question of how to create and administer a just society (Kant& Rawls). Some have explored the interesting nature of beingand how to be true to that essential nature (Spinoza &Heidegger). Many have debated and explored the nature of languageand how it impacts society and power (Wittgenstein & Foucault).And others have made as their major project the creation of a newman who transforms society hopefully for the better (Hegel &Marx).
