Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope and diverse interests that, when taken together, seek an understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases.
Psychology appeared to be a jungle of confusing, conflicting, and arbitrary concepts. These pre-scientific theories doubtless contained insights which still surpass in refinement those depended upon by psychiatrists or psychologists today. But who knows, among the many brilliant ideas offered, which are the true ones? Some will claim that the statements of one theorist are correct, but others will favour the views of another. Then there is no objective way of sorting out the truth except through scientific research.

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.

Western psychologists accuse religion of repressing the vital energy of man and rendering his life quite miserable as a result of the sense of guilt which especially obsesses the religious people and makes them imagine that all their actions are sinful and can only be expiated through abstention from enjoying the pleasures of life. Those psychologists add that Europe lived in the darkness of ignorance as long as it adhered to its religion but once it freed itself from the fetters of religion, its emotions were liberated and accordingly it achieved wonders in the field of production.
