Mathematical Principles

First we will show that posterior old philosophies of the daily pay-socrticos and of Scrates (470 – 399 B.C.), as of Plato and of Aristotle they had defined the time as something that depends on the movement of the bodies to exist, that is, as if movement determined the change of the hours, days, months and years. Moreover, as much the platonic philosophy as the aristotelian one had appraised that the necessary soul to exist, since for they it are only the capable one to understand the numeration of the movements. In according to place, we intend to display as the time was appraised in the Average Age, for Christian philosophers of the Church Catholic, as Saint Augustin and Santo Toms de Aquino, who had used its faith in God in its philosophy; accepting of critical form what it is written in Sacred the Writing and speculating on it in search of the full agreement of the Creation and that was created by the deity. finally, we will analyze as that the philosophy contemporary of Newton defined the mentioned subject already. We will try, over all, to show to which the critical ones of this philosopher with respect to the medieval ones and the old ones that they had appraised what we are in relating in this article of different or similar forms.

But also we intend to present which the definition of Newton, a time that in Mathematical Principles it leaves its concept clearly. 2.Plato and Aristotle: time and movement of the bodies In Timeu Plato (428 – 347 B.C.) define its cosmology. In this the time has the one cosmological origin, being an imperfect copy of the perfect model that is the divine eternity and being born from when the deity it commanded the chaos. Therefore that in this same workmanship, Plato, defend that the time can according to be measured movement of the astros, Sun, Moon and the stars.
