You don't need to take an undergraduate course to understand basics like capitalization (i.e sometimes people value stuff now because they think it will make them more money in future, and people will be willing to sell it for less because they have different expectations, risk tolerance or investment opportunities available to them.. its not exactly one of the more controversial or less practically applied parts of economic theory). But you probably want to read an introductory text, not the guy who pronounces that it's part of the heresy of "economics" and then constructs a straw man version of the theory that actually misses the most important bits.
