A wise move would be to abandon the old but also the newer social-behavioural categorization of psychology; psychology is the core of modern, yet little coordinated sciences of man. The wise wish to dispose of the conjunction 'and' between experience and behaviour (behaviour and experience) in psychological research; a wise possibility would be a thorough application of the psycho-regulatory concept of behaviour that uses method integration in the study of human activity. The wisest would be to perceive personality with its self as the highest priority, to see it as a target or context of all psychological activity. The author elaborates the category of the system psycho-regulators of behaviour as a form of integrating some factorial traits with virtues proven by the development of humanism; apart from wisdom these include conscience, tolerance, pro-social attitude, moderation, humility, etc.
