“The dream has a very striking way of dealing with the category of opposites and contradictions. This is simply disregarded. To the dream 'No' does not seem to exist. In particular, it prefers to draw opposites together into a unity or to represent them as one. Indeed, it also takes the liberty of representing some random element by its wished-for opposite, so that at first one cannot tell which of the possible poles is meant positively or negatively in the dream-thoughts.”

“A truth is not necessary, because we negatively are not able to conceive the actual existence of the opposite thereof;but a truth is necessary when we positively are able to apprehend that the negation thereof includes an inevitable contradiction. It is not that that we can see how the opposite comes to be true, but it is that the opposite can not possibly be true.”

“What are the inner man and woman? Our being consists of two energies: the male and female aspect. Irrespective of if we are a man or a woman, we have both a male and female side.Life develops through opposite poles and tendencies for example yes and no, joy and sorrow, light and darkness, positive and negative, day and night and life and death.Just as electricity needs both a negative and positive pole for a spark to arise, the human consciousness has also two poles. These two poles are the male and female side. The right side of the body represents the male side and the left side of the body represents the female side. We all have both a male and female side, which is represented by the right and left side of the body.”

“That all opposites—such as mass and energy, subject and object, life and death—are so much each other that they are perfectly inseparable, still strikes most of us as hard to believe. But this is only because we accept as real the boundary line between the opposites. It is, recall, the boundaries themselves which create the seeming existence of separate opposites. To put it plainly, to say that "ultimate reality is a unity of opposites" is actually to say that in ultimate reality there are no boundaries. Anywhere.”

“...it is not possible to create the opposite of what one has always known, simply because the opposite is believed to be desired. Human beings need what they already know, even horrors.”

“In both jokes and dreams, Freud observed, meanings are condensed and displaced, things are represented indirectly or by their opposites, fallacious reasoning trumps logic. Jokes often arise involuntarily, like dreams, and tend to be swiftly forgotten. From these similarities Freud inferred that jokes and dreams share a common origin in the unconscious. Both are essentially means of outwitting our inner "censor.”
