The idea and the feeling of freedom play such a part in the life of man that he is ready to sacrifice in their name his own life and still more frequently that of his fellow-men. Man feels that he is really man only when he is able to realize himself indivi dually, socially and cosmically in a complete freedom, i. e. according to the inner bio-psychical depths of his own being without any constraint from the outer - social or (...) cosmic - world. However, although people like very much, and often too much, to speak about freedom, its content and limits are so vague for most of them that everybody determines the content and limits of freedom according to his own tastes, dispositions and interests. Perhaps just because of this vagueness of the idea of freedom, this idea has such a great influence on man, giving a free play to his imagination. Therefore, it would be good to clarify the idea of freedom by analysing its different aspects in their connection with the general problem of determinism and indeterminism. (shrink)
