For example, although Freud did not discover the unconscious mind, he drew much attention to the nature of unconscious thought and emotion. He also focused on repression , which he felt was the basis of many psychological symptoms. Any kind of restrictions on a person's behavior became suspect, and consequently many restrictions required by Jewish law came under criticism. This was actually a distortion of the theory. It is one thing to repress , and another thing to suppress .
Suppression means to exert conscious, voluntary control.
A human being is not an animal in the jungle which tries to satisfy every desire as long as it can get away with it. In order to live a decent life, in order to live in society, it is necessary to suppress. On the other hand, repression is an unconscious force. In other words, a person may be so frightened of harboring a particular thought or feeling that he doesn't want to admit its existence even to himself. It resides in his unconscious mind, where it exists without his awareness.
