Background[ edit ] Although it influenced the course of subsequent German philosophy dramatically, exactly how to interpret this concept was a subject of some debate among 20th century philosophers. Kant first describes it in his Critique of Pure Reasonand distinguished his view from contemporary views of realism and idealismbut philosophers do not agree how sharply Kant differs from each of these positions. Transcendental idealism is associated with formalistic idealism on the basis of passages from Kant's Prolegomena to any Future Metaphysicsalthough recent research has tended to dispute this identification. Transcendental idealism was also adopted as a label by the subsequent German philosophers Johann Gottlieb Fichte and Friedrich Wilhelm Joseph von SchellingArthur Schopenhauerand in the early 20th century by Edmund Husserl in the novel form of transcendental-phenomenological idealism.
Indeed, it reads more like the report of an intuition than a formal proof. Descartes underscores the simplicity of his demonstration by comparing it to the way we ordinarily establish very basic truths in arithmetic and geometry, such as that the number two is even or that the sum of the angles of a triangle is equal to the sum of two right angles.
We intuit such truths directly by inspecting our clear and distinct ideas of the number two and of a triangle. So, likewise, we are able to attain knowledge of God's existence simply by apprehending that necessary existence is included in the clear and distinct idea of a supremely perfect being.

The distinction between possible or contingent existence on the one hand, and necessary existence on the other, allows Descartes to account for the theological difference between God and his creatures. Descartes: Relationship Between Mind and Body - In Meditation Six entitled “Concerning the Existence of Material Things, and Real Distinction between the Mind and Body”, one important thing Descartes explores is the relationship between the mind and body.
As Descartes writes in the Fifth Meditation: Certainly, the idea of God, or a supremely perfect being, is one that I find within me just as surely as the idea of any shape or number. And my understanding that it belongs to his nature that he always exists is no less clear and distinct than is the case when I prove of any shape or number that some property belongs to its nature AT 7: Descartes does not conceive the ontological argument on the model of an Euclidean or axiomatic proof, in which theorems are derived from epistemically prior axioms and definitions.
On the contrary, he is drawing our attention to another method of establishing truths that informs our ordinary practices and is non-discursive. This method employs intuition or, what is the same for Descartes, clear and distinct perception. It consists in unveiling the contents of our clear and distinct ideas.
The basis for this method is the rule for truth, which was previously established in the Fourth Meditation. According to the version of this rule invoked in the Fifth Meditation, whatever I clearly and distinctly perceive to be contained in the idea of something is true of that thing.
So if I clearly and distinctly perceive that necessary existence pertains to the idea of a supremely perfect being, then such a being truly exists. Although Descartes maintains that God's existence is ultimately known through intuition, he is not averse to presenting formal versions of the ontological argument.
He never forgets that he is writing for a seventeenth-century audience, steeped in scholastic logic, that would have expected to be engaged at the level of the Aristotelian syllogism. Descartes satisfies such expectations, presenting not one but at least two separate versions of the ontological argument.
These proofs, however, are stunningly brief and betray his true intentions. One version of the argument simply codifies the psychological process by which one intuits God's existence, in the manner described above: Whatever I clearly and distinctly perceive to be contained in the idea of something is true of that thing.
I clearly and distinctly perceive that necessary existence is contained in the idea of God. When presenting this version of the argument in the First Replies, Descartes sets aside this first premise and focuses our attention on the second.
In so doing, he is indicating the relative unimportance of the proof itself. Having learned how to apply Descartes' alternative method of reasoning, one need only perceive that necessary existence pertains to the idea of a supremely perfect being.
Once one attains this perception, formal arguments are no longer required; God's existence will be self-evident Second Replies, Fifth Postulate; AT 7:Trademark Notice: Product or corporate 4 Descartes on the Formal Reality, Objective Reality, and The key, he argues, is Descartes’ distinction between the truth and falsity of things and.
The distinction between possible or contingent existence on the one hand, and necessary existence on the other, allows Descartes to account for the theological difference between God and his creatures.
In scientific discourses theoretical concepts are not true or false elements or pictures of some part of reality, but are constructions designed to do a job the best possible way.
Different conceptions of fundamental terms like information are thus more or less fruitful depending on what theories (and in the end what practical actions) they are expected . He adds later that the unity of God's will and understanding "is another way in which the meditator can recognize the collapse of the distinction between the objective reality of the idea of God and the formal reality of its cause" ().
If we try to keep within the framework of what can be proved by the Kantian argument, we can say that it is possible to demonstrate the empirical reality of space and time, that is to say, the objective validity of all spatial and temporal properties in mathematics and physics.
The causal principle means that every idea has a cause and that every idea must have at least a cause which has at least as much formal reality as the idea has objective reality.
In the causal principle, Descartes argue that his idea of God must have been caused by God.
