Ego and Superego

According to Freud, the mind is made up of the id, the ego, and the superego. The id is concerned with satisfying our needs, the ego is aware of the self and the world, and the superego is concerned with morality.

Creative ideas originate in the unconscious id and must be filtered through the ego and superego before they can be expressed to the world. The ego may reject an idea because it is unrealistic or impractical and the superego may reject an idea because it is against our ethics.

For example, an idea to genetically engineer a purple cat might be rejected by the ego for being impossible. The idea to throw a cat into a vat of purple paint would be rejected by the superego for being cruel.

Very few creative ideas will get past an overly restrictive ego and superego. At the same time, an excessively passive ego or superego will result in the expression of many impractical or immoral ideas. Through exercises such as brainstorming [ For more on 'brainstorming' go here: http://www.braingle.com/mind/84.html ], we can train our ego and superego to be more or less selective depending upon our needs.
