the history of science have one common feature: they deconstruct our convictions about our own self-importance. Copernicus moved our home from centre of the universe to its periphery, Darwin relegated us to descent from an animal world and Freud discovered the unconscious and deconstructed the myth of a fully rational mind. In Freud's view, human beings are basically irrational and the unconscious mind is alogical. We are forever driven by irrational, practically uncontrollable unconscious instincts that are the ultimate cause of all activity. Rogers sees human beings as basically rational and behaviour is controlled through reason. Rationality and the actualising tendency are inseparably connected in Rogers' basic image of personality. Human behaviour is, according to Rogers: "exquisitely rational, moving with subtle and ordered complexity toward the goals the organism is endeavouring to achieve". The natural course of the actualising tendency is, however, often blocked by psychosocial conditions. When this happens, people become estranged from their true nature and may behave irrationally through anti-social and destructive behaviour. Hidden Personalities The Freudian concept of the unconscious mind was never experimentally verified by him and remained a theoretical construct. Critical questions about what is available to immediate observation and what occurs unconsciously could never be fully answered by Freud as he did not possess any of the current day technological possibilities. Through contemporary cognitive science, it has been discovered that most of our thought actually is unconscious, not in the Freudian sense of being repressed, but in the sense that it operates beneath the level of cognitive awareness, inaccessible to consciousness and operating too fast to focus on. Unconscious processing goes on in the mind of humans, not because we have to filter out threatening stimuli and impulses, but because many cognitive operations go on without conscious participation. The brain operates in this way in order not to flood the conscious part of the mind with impressions. The unconscious is a type of process, a way of constructing perception, memories and other kinds of cognition, not a portion of the mind. This view agrees with Roger's concept of the unconscious, who theorised that the unconscious is only a part of the phenomenological field and does not control our personality. Aside from Freud and Roger's views on the hidden personality there is a simplified idea of stress. When our hidden personality emerges it is also referred to as out-of-character episodes. These are essential to
