“Constructive Alternativism: the idea that, while there is only one true reality, reality is always experienced from one or another perspective.What was realised by Kelly was that every individual acts, reacts and behaves according to how they view their own reality. Each person views another or an event in an entirely different way to anyone else. But what forms that basic reality was of course needed to be understood.”

“To rule out the possibility of belief in another's reality is to encapsulate that reality and, thus, to impose implicity the hegemony of one's own view of the world.”

“The belief that one’s own view of reality is the only reality is the most dangerous of all delusions.”

“One person's dream is another's reality.”

“One person's craziness is another person's reality.”

“No one feels another's grief, no one understands another's joy. People imagine that they can reach one another. In reality they only pass each other by.”

“Maybe each human being lives in a unique world, a private world different from those inhabited and experienced by all other humans. . . If reality differs from person to person, can we speak of reality singular, or shouldn't we really be talking about plural realities? And if there are plural realities, are some more true (more real) than others? What about the world of a schizophrenic? Maybe it's as real as our world. Maybe we cannot say that we are in touch with reality and he is not, but should instead say, His reality is so different from ours that he can't explain his to us, and we can't explain ours to him. The problem, then, is that if subjective worlds are experienced too differently, there occurs a breakdown in communication ... and there is the real illness.”
