Thomas Aquinas (read as Tomas Akuinas) is a very important thinker who has deeply influenced the whole history of philosophy after himself. It is not right to compare the magnitude of his influence with that of Aristotle, which, of course, has benefited much more than his considerations. Nevertheless, Thomas Aquinas has a rightful reputation as a philosopher who has best interpreted Aristotle. The name Thomas Aquinas is the name commonly used by the major philosophical historians in the West. Apart from Thomas Aquinas, Thomas with Aquino, only Thomas and Aquinian Tommasso are used to describe him. Here we prefer a name commonly used by medieval philosophers, which we regard as trustworthy and credible. The name Aquinas comes from Aquinum, where he was born. Thomas Aquinas was born in 1224 or 1225. In some sources, the year 1226 is also mentioned. Aquinas' father, Roccasecca and Montesangiovanni dominated the region. Annesi Theodora (d., 1255) came from the Caracciolo dynasty of Naples. His grandfather, Francesca de Suabia, was Barbarossa's sister. It is understood from this that Thomas Aquinas is not only an epochal philosophically important identity; but it also draws attention as an important political personality of the period. However, he has chosen a life away from politics by repeating that many philosophers have done in the past.
