Psychology is an academic and applied discipline involving the scientific study of mental processes and behavior. Psychologists study such phenomena as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Psychology also refers to the application of such knowledge to various spheres of human activity, including problems of individuals' daily lives and the treatment of mental health problems.

- How such an elaborate theory could have become so widely accepted – on the basis of no systematic evidence or critical experiments, and in the face of chronic failures of therapeutic intervention in all of the major classes of mental illness... – is something that sociologists of science and popular culture have yet to fully explain.

- Is it dangerous to claim that parents have no power at all (other than genetic) to shape their child's personality, intelligence, or the way he or she behaves outside the family home? ... A confession: When I first made this proposal ten years ago, I didn't fully believe it myself. I took an extreme position, the null hypothesis of zero parental influence, for the sake of scientific clarity. ... The establishment's failure to shoot me down has been nothing short of astonishing.
- Psychoanalysis provides truth in an infantile, that is, a schoolboy fashion: we learn from it, roughly and hurriedly, things that scandalize us and thereby command our attention. It sometimes happens, and such is the case here, that a simplification touching upon the truth, but cheaply, is of no more value than a lie. Once again we are shown the demon and the angel, the beast and the god locked in Manichean embrace, and once again man has been pronounced, by himself, not culpable.

- One can ask two different kinds of questions with regard to the topics of study in psychology as well as in other sciences. One can ask for the phenomenal characteristics of psychological units or events, for example, how many kinds of feelings can be qualitatively differentiated from one another or which characteristics describe an experience of a voluntary act. Aside from this are the questions asking for the why, for the cause and the effect, for the conditional-genetic interrelations. For example, one can ask: Under which conditions has been a decision made and which are the specific psychological effects which follow this decision? The depiction of phenomenal characteristics is usually characterized as “description”, the depiction of causal relationships as “explanation.”

- The popular medical formulation of morality that goes back to Ariston of Chios, "virtue is the health of the soul," would have to be changed to become useful, at least to read: "your virtue is the health of your soul." For there is no health as such, and all attempts to define a thing that way have been wretched failures. Even the determination of what is healthy for your body depends on your goal, your horizon, your energies, your impulses, your errors, and above all on the ideals and phantasms of your soul. Thus there are innumerable healths of the body; and the more we allow the unique and incomparable to raise its head again, and the more we abjure the dogma of the "equality of men," the more must the concept of a normal health, along with a normal diet and the normal course of an illness, be abandoned by medical men. Only then would the time have come to reflect on the health and illness of the soul, and to find the peculiar virtue of each man in the health of his soul.

- Despite the burgeoning technologies in the field of "helping", on many levels psychotherapy is still a crapshoot. Some of the goal of training, I think, is to help students accept that fact. The work is part science, part art, and part luck. Learning to tolerate the anxiety inherent in that recipe is critical for any clinician.
