Tuesday classes

For History of Philosophy II today we were discussing Kant's conception of our categories of Understanding and how this structure in our minds is itself structured. An example of how education is supposed to effect this structure is the famous lecture by David Foster Wallace This is Water where he argues an education enables you to take control over how you perceive the world around you. And is one of the main reasons for it. But Wallace is gone by his own hand. How does this reflect on the paradigm of meaning that he espouses in This is Water? Why did he kill himself? For Introduction to Philosophy today we discussed Scholasticism and Aquinas. My question is, are today's physicists conceptions of the forces of the universe roughly a continuation of what Aquinas considers Angels?
