Brust’s Law is as follows: Truth is counter-intuitive.
I remember the first time a teacher explained to me that a gas took up more volume per weight than the same substance as a solid. That was obviously ridiculous; gas is malleable, so clearly it can be pressed into a smaller space than a solid would. Right? Of course, further explanation clarified the matter.
I remember Clausewitz explaining that wars are always started by the defender, which is blatantly absurd–and also true. The one who attacks doesn’t want a war, he wants, for example, to conquer territory, or control resources, or subjugate a population. If the one who was attacked simply permitted this to happen, there would be no war.
It is absurd to think that a single cell organism could, over eons, evolve into a human being.
It is preposterous to think that an object heavier than air could fly.
But, there it is, truth is counter-ntuitive, and it only becomes intuitively obvious when we begin to understand the subject well enough to change our intuitions.
It seems intuitively obvious that, if you raise the labor cost (ie, wages) of a commodity, the price of the commodity will rise. Intuitively obvious, but wrong (even the bourgeois economists stopped trying to sell “the wage-price spiral” after about 1977). Why? Don’t worry, we’ll get there. But for now, as we go through Capital, when something strikes you as counter-intuitive, that means it is something to pay close attention to, not a reason to shut down your brain.
