Immanuel Kant: Critique of Pure Reason

Immanuel Kant was a prussian philosopher who's regarded as one the central figures of Englightenment. His output on ethics, metaphysics and epistemology have cemented hes place as one of the greats and for many he truly is the greatest to ever live. His magnum opus, Critique of Pure Reason, takes on the difficult task of trying to discover the answer to the mind boggling question: what can we know?   

Throughout this journey we will stumble on concepts and ideas such as pure intuitions, a priori, a posteriori, worlds of noumena and phenomena and ding an sich as we build the foundation of transcendental idealism. 

"Thoughts without content are empty, intuitions without concepts are blind."
