Religion is the opium of the masses.

Religion is the opium of the masses.

If you can cut the people off from their history, then they can be easily persuaded.

Since only what is material is perceptible, knowable, nothing is known of the existence of God.

Men make their own history, but they do not make it just as they please; they do not make it under circumstances chosen by themselves, but under circumstances directly encountered, given and transmitted from the past. The tradition of all the dead generations weighs like a nightmare on the brain of the living.

In proportion as the exploitation of one individual by another is put an end to, the exploitation of one nation by another will also be put an end to. In proportion as the antagonism between classes within the nation vanishes, the hostility of one nation to another will come to an end.

The social revolution...cannot draw its poetry from the past, but only from the future. It cannot begin with itself before it has stripped itself of all superstitions concerning the past.
