We have long observed that every neurosis has the result, and therefore probably the purpose, of forcing the patient out of real life, of alienating him from actuality.

That which we can't remember, we will repeat.

The ego is not master in its own house.

We are never so defensless against suffering as when we love.

There 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.

The goal towards which the pleasure principle impels us - of becoming happy - is not attainable: yet we may not - nay, cannot - give up the efforts to come nearer to realization of it by some means or other.

The mind is like an iceberg, it floats with one-seventh of its bulk above water.
