Metaphysical solipsism Metaphysical solipsism is a variety of solipsism. Based on a philosophy of subjective idealismmetaphysical solipsists maintain that the self is the only existing reality and that all other realities, including the external world and other persons, are representations of that self, and have no independent existence. Epistemological solipsism Epistemological solipsism is the variety of idealism according to which only the directly accessible mental contents of the solipsistic philosopher can be known.
Clear and Distinct Ideas At the outset of the Third Meditation, Descartes tried to use this first truth as the paradigm for his general account of the possibilities for achieving human knowledge.
In the cogito, awareness of myself, of thinking, and of existence are somehow combined in such a way as to result in an intuitive grasp of a truth that cannot be doubted.
Perhaps we can find in other cases the same grounds for indubitable truth. But what is it? Considered formally, as the content of my thinking activity, the ideas involved in the cogito are unusually clear and distinct.
III But ideas may also be considered objectively, as the mental representatives of things that really exist. According to a representative realist like Descartes, then, the connections among our ideas yield truth only when they correspond to the way the world really is.
But it is not obvious that our clear and distinct ideas do correspond to the reality of things, since we suppose that there may be an omnipotent deceiver. In some measure, the reliability of our ideas may depend on the source from which they are derived.
René Descartes was born in La Haye en Touraine (now Descartes, Indre-et-Loire), France, on 31 March His mother, Jeanne Brochard, died soon after giving birth to him, and so he was not expected to survive. Descartes' father, Joachim, was a member of the Parlement of Brittany at Rennes. René lived with his grandmother and with his great-uncle. 2 - To Descartes, the idea of "reality" is tied in with a hierarchy of independence of existence. That which is lower down in this hierarchy depends on its existence, and has less than, or equal, reality than that which is higher up in the hierarchy.

Descartes held that there are only three possibilities: God Exists The next step in the pursuit of knowledge, then, is to prove that god does indeed exist. But since my idea of god has an absolutely unlimited content, the cause of this idea must itself be infinite, and only the truly existing god is that.
In other words, my idea of god cannot be either adventitious or factitious since I could neither experience god directly nor discover the concept of perfection in myselfso it must be innately provided by god.
From the cogito I know that I exist, and since I am not perfect in every way, I cannot have caused myself. So something else must have caused my existence, and no matter what that something is my parents?
The chain of causes must end eventually, and that will be with the ultimate, perfect, self-caused being, or god. As Antoine Arnauld pointed out in an Objection published along with the Meditations themselves, there is a problem with this reasoning.
Since Descartes will use the existence and veracity of god to prove the reliability of clear and distinct ideas in Meditation Four, his use of clear and distinct ideas to prove the existence of god in Meditation Three is an example of circular reasoning. We must rely on a non-deceiving god only as the guarantor of veridical memorywhen a demonstrative argument involves too many steps to be held in the mind at once.
But this response is not entirely convincing. I now know that there really is a being powerful enough to deceive me at every turn. But Descartes argued that since all perfections naturally go together, and since deception is invariably the product of imperfection, it follows that the truly omnipotent being has no reason or motive for deception.
God does not deceive, and doubt of the deepest sort may be abandoned forever.2 - To Descartes, the idea of "reality" is tied in with a hierarchy of independence of existence. That which is lower down in this hierarchy depends on its existence, and has less than, or equal, reality than that which is higher up in the hierarchy.
An idea of God has infinite objective reality; an idea of your cousin, assuming you have one, has finite objective reality; and idea of red has modal objective reality.
The concept of objective reality is crucial to Descartes' causal argument for the existence of God. Since Descartes will use the existence (and veracity) of god to prove the reliability of clear and distinct ideas in Meditation Four, his use of clear and distinct ideas to prove the existence of god in Meditation Three is an example of circular reasoning.
Descartes gives at least two arguments for God's existence. The first one, found in I, is a version of the ontological argument for God's existence. Descartes' ontological argument goes as follows: (1) Our idea of God is of a perfect being, (2) it is more perfect to exist than not to exist, (3) therefore, God must exist.
