This method he has developed for the Sciences. His aim is to apply a method to demonstrate these two truths, in a so clear and evident manner that result to be evident.


He further indicates how the very Scriptures say that the mind of man is sufficient to discover God. Moreover, the believers could be accused of making a circular reasoning, when saying that we must believe in God because of the Scriptures, and in the authority of the Scriptures because they have been inspired by God. His first consideration is that the existence of God has to be demonstrated philosophically, besides the theological reasons for belief, particularly if we consider to make a demonstration for the non-believers. To the most wise and illustrious the Dean and Doctors of the Sacred Faculty of Theology in Parisĭescartes says that he is asking the protection of the Faculty for his work, and to this end he writes the present dedication. Letter of Dedication and Preface Letter of dedication Descartes' metaphysical thought is also found in the Principles of Philosophy (1644), which the author intended to be a philosophical guidebook. The book consists of the presentation of Descartes' metaphysical system at its most detailed level and in the expanding of his philosophical system, first introduced in the fourth part of his Discourse on Method (1637). (In fact, Descartes began work on the Meditations in 1639.) One of the most influential philosophical texts ever written, it is widely read to this day. He wrote the meditations as if he had meditated for six days: each meditation refers to the last one as "yesterday". The book is made up of six meditations, in which Descartes first discards all belief in things that are not absolutely certain, and then tries to establish what can be known for sure. The title may contain a misreading by the printer, mistaking animae immortalitas for animae immaterialitas, as suspected by A. The French translation (by the Duke of Luynes with Descartes' supervision) was published in 1647 as Méditations Métaphysiques. Meditations on First Philosophy, in which the existence of God and the immortality of the soul are demonstrated ( Latin: Meditationes de Prima Philosophia, in qua Dei existentia et animæ immortalitas demonstratur) is a philosophical treatise by René Descartes first published in Latin in 1641.
