Descartes cosmological argument

Descartes cosmological argument is an argument from

causation

P1 Descartes

the cause of my existence of a thinking thing must be a)myself b) I have always existed c) my parents d)a being less than God e) God

P2 Descartes

I cannot have caused myself to exist for I would have created myself perfect, nor can I sustain my own existence for then I would be God

P3 Descartes

Neither have I always existed for I would be aware of this

P4 Descartes

My parents may be the cause of my physical existence but not of me as a thinking mind

P5 Descartes

I cannot be created by a being less than God as I have the idea of God inside me and their must be as much reality in the cause as the effect

C Descartes

by elimination, only God could have created me
