I have found little that is good about human beings on the whole

Being hit by some recent turns in science politics I remember a quote by Freud

“I have found little that is ‘good’ about human beings on the whole. In my experience most of them are trash, no matter whether they publicly subscribe to this or that ethical doctrine or to none at all. That is something you can not say aloud, or perhaps even think, though your experience of life can hardly have been different than mine.”

The source, however, is difficult to find – a letter to Oskar Pfister on Oct, 9, 1918 published in: Psychoanalysis and Faith: The Letters of Sigmund Freud and Oskar Pfister, eds. Heinrich Meng and Ernst L. Freud, trans. by Eric Mosbacher. New York: Basic Books, 1963. The German version is being published in Sigmund Freud, Oskar Pfister, Briefe 1909-1939, Fischer, Frankfurt am Main 1963, 2. Aufl. S. 62.

Ich zerbreche mir nicht viel den Kopf über Gut und Böse, aber ich habe an den Menschen durchschnittlich wenig ‚Gutes‘ gefunden. Die meisten sind nach meinen Erfahrungen Gesindel, ob sie sich laut zu dieser, jener oder keiner ethischen Lehre bekennen.

seems to be the same opinion as in Romans 3:10

καθὼς γέγραπται ὅτι οὐκ ἔστιν δίκαιος οὐδὲ εἷς
