● The world deteriorates and is headed for a collapse (according to
Plato the world recedes from its idea which was its model).
● The world develops and pursues an excellence (according to
Aristotle the world approaches its form which is its goal).
● The world develops and deteriorates at the same time (according to
Heraclitus the opposites coexist in each entity and in the whole world).
● The world does not exist (according to
Parmenides only timeless, uniform, necessary, and unchanging unity exists).
● “I know that I know nothing” (according to
Socrates there is no an absolute certainty but only a partial confidence).
