"Johann Herbart’s work on education and particularly mathematical psychology influenced me. I think mathematics is the pure instance of construct functioning—the model of human behaviour."

“Out of all this I have gradually developed the notion that psychology is pretty much confined to the paradigms it employs and, while you can take off in a great many directions and travel a considerable distance in any of them — as indeed we have with stimulus-response psychology — there is no harm in consorting with a strange paradigm now and then. Indeed the notion has occurred to me that psychology may best be regarded as a collection of paradigms wooed by exphysicists, ex-physiologists, and ex-preachers, as well as a lot of other intellectual renegades. Even more recently it has struck me that this is the nature of man; he is an inveterate collector of paradigms.”

“While we could agree with the psychological phenomenologists and assign an important place to generalization within the realm of the individual, we were quite sure that some data must be lifted from the realm of the individual and construed nomothetically that is, in a realm comprising many individuals.”

“Diagnosis is all too frequently an attempt to cram a whole live struggling client into a nosological category.”

“There is another meaning that might be attached to this admonition to be oneself; that one should not try to disguise himself. I suspect this comes nearer to what psychologists mean when they urge people to be themselves. It is presumed that the person who faces the world barefaced is more spontaneous, that he expresses himself more fully, and that he has a better chance of developing all his resources if he assumes no disguises.”

“Is it a phenomenological theory? Granted that... phenomenology comes from various shapes and sizes, our fundamental postulate does not make the usual phenomenological commitments. We did not say, for example, that one is surrounded only by his perceptions. In fact, we started this discussion by asserting that there is a sense in which all of us are caught up in our circumstances. Nor do we say that each personal world is an island universe. The words 'personal' and 'private' are certainly not synonyms. I think the tree that falls in the primeval forest makes a bang just like any other tree. Moreover. we might sometimes, although at the moment cannot say how, take an interest in the noise that centuries ago nobody heard and eventually makes something scientifically important out of it.”

“It is important, then, to see confirmation, or the validation of one’s constructs, as securing a base upon which one can build major revisions of construct system. This is why we so often cite security as necessary for broad advancement, whether in a person or in society. This is why the arts and sciences flourish at a higher level when nations and people are led to believe they are on the right track.”
