Though not his most famous book, Civilization and Its Discontents, written in 1929-1930, is probably the most frequently read work by Sigmund Freud, for it appears to speak directly to the human condition.
It seems certain that we do not feel comfortable in our present-day civilization, but it is very difficult to form an opinion whether and in what degree men of an earlier age felt happier, and what part their cultural conditions played in the matter. We shall always tend to consider people’s distress objectively—that is, to place ourselves, with our own wants and sensibilities, in their conditions, and then to examine what occasions we should find in them for experiencing happiness or unhappiness.
This method of looking at things, which seems objective because it ignores the variations in subjective sensibility, is, of course, the most subjective possible, since it puts one’s own mental states in the place of any others, unknown though they may be. Happiness, however, is something essentially subjective. No matter how much we may shrink with horror from certain situations—of a galley-slave in antiquity, or a peasant during the Thirty Years’ War, of a victim of the Holy Inquisition, of a Jew awaiting a pogrom—it is nevertheless impossible for us to feel our way into such people. …
For a wide variety of reasons, it is very far from my intention to express an opinion upon the value of human civilization. I have endeavoured to guard myself against the enthusiastic prejudice which holds that our civilization is the most precious thing that we possess or could acquire and that its path will necessarily lead to heights of unimagined perfection. … One thing only do I know for certain, and that is that man’s judgments of value follow directly his wishes for happiness—that, accordingly, they are an attempt to support his illusions with arguments. …
The fateful question for the human species seems to me to be whether and to what extent their cultural development will succeed in mastering the disturbance of their communal life by the human instinct of aggression and self-destruction. It may be that in this respect precisely the present time deserves a special interest. Men have gained control over the forces of nature to such an extent that with their help they would have no difficulty in exterminating one another to the last man. They know this, and hence comes a large part of their current unrest, their unhappiness and their mood of anxiety.
