Before the new principle could achieve mastery, Rousseau had made mastery impossible.

Two men came into the world at this very moment, whom destiny made incarnations of the discordant principles.

Danton and Robespierre were both born in 1759.
Diderot seems to have had a biblical presentiment, says Michelet.

"We feel that he saw, beyond Rousseau, something sinister, a spectre of the future.

Diderot-Danton already looks in the face of Rousseau-Robespierre."[147] A more vexatious incident now befell the all-daring, all-enduring Diderot, than either the decree of the Council or the schism of the heresiarch at Montmorency.
