Both are obligatory, but the latter much more so than the former; for that is the fundamental principle,[21117] "the incentive which sustains and impels a democratic and popular government." It is impossible to apply the social contract if everybody does not scrupulously observe the first clause of it, namely, the complete surrender of himself to the community; everybody, then, must give himself up entirely, not only actually but heartily, and devote himself to the public good, which public good is the regeneration of Man as we have defined it.

The veritable citizen is he who thus marches along with us.

With him, as with us, abstract truths of philosophy control the conscience and govern the will.

He starts with our articles of faith and follows them out to the end; he endorses our acts, he recites our creed, he observes our discipline, he is a believing and practicing Jacobin, an orthodox Jacobin, unsullied, and without taint of heresy or schism.
Never does he swerve to the left toward exaggeration, nor to the right toward toleration; without haste or delay he travels along the narrow, steep and straight path which we have marked out for him; this is the pathway of reason, for, as there is but one reason, there is but one pathway.

Let no one swerve from the line; there are abysses on each side of it.
