"The mind is like the stomach. It is not how much you put into it that counts, but how much it digests"
About this Quote
The specific intent is quality control. “How much you put into it” targets accumulation as a status move - reading lists, lectures attended, newspapers devoured. “How much it digests” shifts the measure to transformation: can you metabolize an idea into judgment, character, or action? Digestion implies time, friction, even discomfort. Some inputs won’t agree with you; some will. The point is not purity but process.
Subtextually, Nock is also skeptical of institutions that equate exposure with understanding. In his early-20th-century context - a flood of print, propaganda after World War I, the professionalization of schooling - information becomes cheap, and cheap information becomes a temptation. The quote anticipates a modern pathology: mistaking intake for insight, scrolling for thinking.
The metaphor works because it quietly reassigns responsibility. No one can digest for you. You can be fed, but you still have to do the messy interior work: selecting, breaking down, integrating, and discarding. Intelligence, Nock implies, is less a warehouse than a metabolism.
