'ENERGEIA' AND 'KINESIS' - 'HAPLOS ENERGEIA' AND 'ENERGEIA ATELES' IN ARISTOTLE'S THOUGHT ('Energeia' i 'kinesis', a 'haplos energeia' i 'energeia ateles' w swietle rozwazan Arystotelesa)

The present article attempts to show some of the difficulties connected with Aristotle's distinction between 'energeia' and 'kinesis'. On the basis of an analysis several fragments from the 'Metaphysics', 'Physics', 'De Anima', and 'Nicomachean Ethics', the author comes to the conclusion that the main cause of ambiguities is an unclear division of 'energeia' into 'energeia ateles' and 'haplos energeia'. The author does not offer a definitive solution but suggests that the difficulties are a useful instrument in a deeper reflection on man from the point of view of his activity.
