Die Religion ist der Seufzer der bedrängten Kreatur, das Gemüt einer herzlosen Welt, wie sie der Geist geistloser Zustände ist. Sie ist das Opium des Volks. Die Aufhebung der Religion als des illusorischen Glücks des Volks ist die Forderung seines wirklichen Glücks.
Religion is the sigh of the oppressed creature, the heart of a heartless world, just as it is the spirit of spiritless conditions. It is the opium of the people. To abolish religion as the illusory happiness of the people is to demand their real happiness.

Opium is the only drug to' be rely'd on—all the boasted nostrums only take up time, and as the disease [is] often of short duration, or of small quantity, they have gain'd credit which they do not deserve.

Throw out opium, which the Creator himself seems to prescribe, for we often see the scarlet poppy growing in the cornfields, as if it were foreseen that wherever there is hunger to be fed there must also be a pain to be soothed; throw out a few specifics which our art did not discover, and it is hardly needed to apply; throw out wine, which is a food, and the vapors which produce the miracle of anaesthesia, and I firmly believe that if the whole materia medica [medical drugs], as now used, could be sunk to the bottom of the sea, it would be all the better for mankind,—and all the worse for the fishes.

We can make an exception of opium 'which the creator seems to prescribe, as we often see the scarlet poppy growing in the corn fields' but all other receipts of Omniscience must be condemned. The purple fox-glove, the many-tinted veratrum the lilac stramonium they are all 'noxious' but a little opium it helps the imagination.
