In the case of these excerpts from the great philosophers, when I say I've read them, I mean I've scratched the surface of their thought. I plan on going back to these texts again and again. This has been a great introduction to these thinkers, and from my perspective at the moment, the most interesting aspect of my journey was witnessing the progression from the hard-headed common sense of Francis Bacon to the -- one could say -- hard-headed mysticism of Immanuel Kant, who concludes that we can have no real knowledge of reality.
