Aristotles

Aristotle was one from the ancient philosophers that influenced so deep science for centuries. His thought by making continuing questions, was occupied with all the techniques of logic and rationalisation of phenomena. His work "Enhiridion" was the main source of study for the scientists since nowadays.

Aristotles believed that everything in the universe was the mix of four elements, the Earth, water, air and fire. These elements had a certain weight; fire was the lightest one and the Earth the heaviest. The various objects take their shape by the combination of these elements and their texture is determined by the dominant element each time, since one of the elements was always dominant. As a result, all the bodies were incomplete. Only the same proportion of the four elements would create a perfect body.

Aristotles' work during Middle Ages

aristotles's universe Aristotles used to believe that the universe remained inalterable from the first moment of its birth. The Earth was its centre, and it was surrounded by all the planets and the stars. Aristotles believed in a natural movement for all the things and this movement was circular. But the imperfection of bodies prevented them from having a perfect circular movement.

However, planets, stars and generally all the celestial bodies were not incomplete. For the reason that they were found in the sky, they had been made by a superior material, that made them perfect and consequently they could move circularly. The Earth however was not perfect, as the other planets, but it remained motionless. Which is the power that made the universe? Aristotles does not answer. This is a point of report and query and nothing more can be added to this.
