A state of consciousness is characteristically very transitory; an idea that is conscious now is no longer so a moment later, although it can become so again under certain conditions that are easily brought about.
Sigmund FreudThere is no doubt that the resistance of the conscious and unconscious ego operates under the sway of the pleasure principle: it seeks to avoid the unpleasure which would be produced by the liberation of the repressed.
Sigmund FreudIt is a mistake to believe that science consists in nothing but conclusively proved propositions, and it is unjust to demand that it should. It is a demand made by those who feel a craving for authority in some form to replace the religious catechism by something else, even a scientific one.
Sigmund FreudReligion restricts the play of choice and adaptation, since it imposes equally on everyone its own path to the acquisition of happiness and protection from suffering. Its technique consists in depressing the value of life and distorting the picture of the real world in a delusional manner - which presupposes an intimidation of the intelligence. At this price, by forcibly fixing them in a state of psychical infantilism and by drawing them into a mass-delusion, religion succeeds in sparing many people an individual neurosis. But hardly anything more.
