“Fraternity has subtleties.”

Things to Come (1936)

Novum Organum (1620), Book I
Context: It cannot be that axioms established by argumentation should avail for the discovery of new works, since the subtlety of nature is greater many times over than the subtlety of argument. But axioms duly and orderly formed from particulars easily discover the way to new particulars, and thus render sciences active.

Anarchist Manifesto (1850)
Variant: Who says antagonism, says civil war
Context: Indeed:
Who says anarchy, says negation of government;
Who says negation of government, says affirmation of the people;
Who says affirmation of the people, says individual liberty;
Who says individual liberty, says sovereignty of each;
Who says sovereignty of each, says equality;
Who says equality, says solidarity or fraternity;
Who says fraternity, says social order;
By contrast:
Who says government, says negation of the people;
Who says negation of the people, says affirmation of political authority;
Who says affirmation of political authority, says individual dependency;
Who says individual dependency, says class supremacy;
Who says class supremacy, says inequality;
Who says inequality, says antagonism;
Who says antagonism, says civil war;
From which it follows that who says government, says civil war.
