While what he says may resonate with you because there is some pseudoscience masquerading as reality (see: Keynesian economics), remember the path he then chose was Scientology. It is OK to say "I don't know". The problem is people want/demand/expect an explanation to everything in the world and once the mask comes off of the societally acceptable narrative, there are hucksters waiting in the wings to sell you their version that you're now extremely susceptible to.
