Meditations on First Philosophy

Meditations on First Philosophy is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Meditations on First Philosophy rather than just read about it. In short: 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), often simply called Meditations on First Philosophy or the Meditations, is a philosophical treatise by René Descartes first published in Latin in 1641.

Key takeaways

  • Meditations on First Philosophy belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Meditations on First Philosophy to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Meditations on First Philosophy from memory before moving on to harder problems.

Reference excerpt

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), often simply called Meditations on First Philosophy or the Meditations, is a philosophical treatise by René Descartes first published in Latin in 1641. The French translation (by the Duke of Luynes with Descartes' supervision) was published in 1647 as Méditations Métaphysiques. The title may contain a misreading by the printer, mistaking animae immaterialitas for animae immortalitas, as suspected by A. Baillet. 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. He wrote the Meditations as if he had meditated for six days: each meditation refers to the last one as "yesterday". (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. 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). Descartes' metaphysical thought is also found in the Principles of Philosophy (1644), which the author intended to be a philosophical guidebook.

Letter of Dedication and Preface

Letter of dedication To the most wise and illustrious the Dean and Doctors of the Sacred Faculty of Theology in Paris Descartes writes the above dedication to ask for the protection of the Faculty for his work. 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. 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. He further indicates how the very Scriptures say that the mind of man is sufficient to discover God. His aim is to apply a method to demonstrate these two truths, in a so clear and evident manner that result to be evident. This method he has developed for the Sciences.

Preface to the reader Descartes explains how he made a mention of the two questions, the existence of God, and the soul, in his Discourse on Method. Following this, he received objections, and two of them he considers are of importance. The first is how he concludes that the essence of the soul is a thing that thinks, excluding all other nature. To this he says that he has a clear perception that he is a thinking thing, and has no other clear perception, and from this he concludes that there is nothing else in the essence of the self. The second is that from the idea I have of something that is more perfect than myself, it cannot be concluded that it exists. In the treatise we will see that in fact from the idea that there is something more perfect than myself, it follows that this exists. It goes on to comment that on a general level the reasoning used by the atheists for denying the existence of God is based in the fact that "we ascribe to God affections that are human, or we attribute so much strength and wisdom to our minds" that we presume to understand that which God can and ought to do. He says that we have to consider God as incomprehensible and infinite, and our minds as limited and finite. Finally, he says that the treatise was submitted to some men of learning to know their difficulties and objections, and are answered at the end of it.

Structure Descartes does not outline the text with a systematic structure. He writes the meditations in a first-person point-of-view, intending for the readers to meditate with him. Thus, the text serves as a handbook of meditative practices—it does not only convey a message, but an experience, too.

Summary and analysis The Meditations is written in the first person, so many authors refer to the arguments as simply spoken by René Descartes, but others consider that he is speaking in the person of an alter ego who they call "the meditator", as is done here sometimes. (Wikipedia is collaboratively edited, so no consistency has been enforced on this.)

Worked examples

Example 1 — a first encounter with Meditations on First Philosophy

Start with the simplest possible case. Write down what Meditations on First Philosophy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Meditations on First Philosophy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Meditations on First Philosophy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Meditations on First Philosophy

In research
Meditations on First Philosophy appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Meditations on First Philosophy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Meditations on First Philosophy is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1641 books, 17th-century books in Latin, Books about consciousness, so understanding it makes those chapters shorter.
In everyday life
Look for Meditations on First Philosophy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
