Full Idea
Truth isn't a reward of free spirits, the child of protracted solitude, nor the privilege of those who have succeeded in liberating themselves. Truth is a thing of this world: it is produced only by virtue of multiple forms of constraint.
Gist of Idea
Truth doesn't arise from solitary freedom, but from societies with constraints

A Reaction
This obviously has a degree of truth in many areas of human belief, but I just don't buy it as an account of Newton's researches into optics, or Lavoisier's chemistry. Politics is more involved once big money is required.
