On a level plain, simple mounds look like hills and the insipid flatness of our present bourgeoisie is to be measured by the altitude of its great intellects.

Marx’s image contrasts real elevation with the illusion of greatness produced by a uniformly low landscape. In a society flattened by bourgeois mediocrity, even small “mounds” can appear as “hills,” so figures celebrated as major intellects may owe their stature less to genuine brilliance than to the diminished standards of their age. The remark functions as a cultural critique: bourgeois social relations, in Marx’s view, narrow horizons and reduce the scale of thought, making modest talents seem monumental. It also implies a comparative measure of an epoch’s vitality—judge the era by the true height of its leading minds, not by the acclaim they receive within a stunted milieu.
