The wealthy man is the man whois much, not the one who has much

There must be something rotten in the very core of a social system which increases its wealth without diminishing its misery

If emancipation of the working classes requires their fraternal conncurrence, how are they to fulfill that great mission with a foreign policy in pursuit of criminal designs, playing upon national prejudices, and squandering in piratical wars the people's blood and treasure? It was not the wisdom of the ruling classes, but the heroic resistance to their criminal folly by the working classes of England, that saved the west of Europe from plunging headlong into an infamous crusade for the propagation of slavery on the other side of the Atlantic.

The religious world is but a reflex of the real world.

Nature is man's inorganic body -- that is to say, nature insofar as it is not the human body. Man lives from nature -- i.e., nature is his body -- and he must maintain a continuing dialogue with it is he is not to die. To say that man's physical and mental life is linked to nature simply means that nature is linked to itself, for man is a part of nature.

The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.

Religion is only the illusory sun which revolves round man as long as he does not revolve round himself.
