What strikes me most about philosophy is in how core it is to everything we do — and this is something I didn’t realize for the longest time. The foundations of the economic, social, and political systems we live in are based upon philosophy; on theories of the nature of man laid down by thinkers such as Rousseau, Kant, and Smith. It turns out that “self evident truths” might actually be philosophical assertions. Philosophy is the first principle upon which many ideas we may initially take for granted rest upon, and I wonder if a general lack of explicit attention and examination on the subject is partially what enables some of the "post truth" attitudes we are seeing today. The more I learn, the more I can relate to "all I know is I know nothing."
