It is better to know than to believe. It is better to understand why rather than just accept the what. Much of the time (though certainly not all the time), the things that we think are obviously and clearly “reality” are actually not. Even when our intuitions are right, we gain much from understanding why they are right. So curious thoughts about why our assumptions are right — and whether they are right — are indeed precisely what people (especially professors) should be thinking and expressing.
