„Socrates said madness was preferable than ‟sober sense‟ because ‟madness comes from the Gods, whereas sober sense is merely human‟ (Fuery xi). From the ancient times until the twenty-first century, people always dealt with – and still deals with – madness in everyday life, and at the same time, it is still girdled with some mystery. As the Greeks thought that it is connected to divine powers, this belief changed during the Middle-Ages and from the eighteenth century it started to be treated rather in a scientific way. However, we do not know the reasons of madness in most of the cases, there are different explanations for the „solutions‟ of mental illnesses. As they have been developing through the centuries, psychopathology began to study these „abnormalities‟ that relates the abnormal function of someone‟s mind and also behaviour (the most common are hysteria, different kinds of personality or eating disorders, syndromes, manias, phobias). In my opinion, the two strangest and most interesting diseases among them are very controversial and often insoluble: they are called schizophrenia and dissociative identity disorder.
