Psychology is a doctrine constructed in linear, logical relationships on the assumption that human thinking is controlled by reason. For example, the attributive, deterministic, internally correlated, causal view explains everything. Of course, each theory creates an associative reality for human vision and perception. The more we appreciate the theory, the more we are constrained by this theory, and the narrower our vision will be accordingly. If you only believe in (psychological) theories and deny other theories, then you are basically a “prisoner” of (psychological) theories. The more deeply one believes in and relies on a theory, the more one’s cognitive ability is slowly narrowed by the theory to a very poor condition. The nature of life or mental phenomena should be a kind of biology, and the understanding of biology is not enough to have logical, rational, linear relations, but must apply those non-linear, disordered, self-assembling, including mutational cognition. Psychology is a theory, moreover, an explanatory system. But it is not the only one, nor is it necessarily the most effective. To some extent, psychology does not bring “mental health” to people. Often people learn a little about psychology (illness) and then put it in their place, and that is what worries me most. What psychology teaches us is that we can be happy without relying on others, without relying on the environment, without relying on material things, and with full acceptance of ourselves and of the outside world. If you believe in (psychology) theory, please study psychology seriously. If you only appreciate psychology and reject other theories, and at the same time have little understanding of psychology, then please do not believe in psychology. The series Another Perspective on the World is not entirely about psychology, but about my own views after studying philosophy, psychology, sociology, culture and so on. Some of the views are even very different from psychology, so please bear with your psychology friends, and don’t take it as psychology to learn from your non-psychology friends.
