Maxim (n.) passed for innate merely because they were self-evident — though nobody ever showed what made them so clear.
Maxim (n.) are useless where ideas are determined and dangerous where they are not — there they confirm and rivet error by their authority.
Maxim (n.) are useless exactly when they are used: 'the whole is bigger than a part' can only convince you of what you already knew.
Maxim (n.) were mistaken for the foundations of science because disputants stopped at them — they were the wall beyond which no one could retreat, not the source from which knowledge sprang.
Maxim (n.) are made of terms no more innate than those of a cat or a weasel; one must wait for time and observation to acquaint one with them.
Maxim (n.) cried up as the great guards of truth reach only the sound of words and not their signification, and so lead a careless use of words into confusion and error.
Maxim (n.) like "it is impossible for the same thing to be and not to be" come late, not early: illiterate people and savages pass many rational years without ever thinking such a thing.
Maxim (n.) are seldom mentioned in the huts of Indians; they are the language and business of the schools, suited to artificial argument and winning disputes, not to discovering truth.
Maxim (n.) are not the foundation of knowledge but its afterthought: knowledge began in the mind with particulars, and general rules only disburden the memory of them.
Maxim (n.) are of great use to stop the mouths of wranglers and of very little use for enlightening the understanding; knowledge would be no less, nor less certain, were they never thought on.
Maxim (n.) prove contradictions when the idea of body is loose, for what is, is lets Descartes demonstrate that there is no vacuum and lets anyone who adds solidity to extension demonstrate that there may be one.
