It should be represented as, “I doubt I think, therefore I am”.
Give more supporting evidence of this doubtful claim is something that I doubt I can do. Let me try. Few people realize the context that this was written. It should be represented as, “I doubt I think, therefore I am”. Why did we drop the doubt? Purge it like an appendage, an unnecessary extension of cognition? Really? Doubt is a pillar of Reason. Do I really need to justify that claim and how it relates to consciousness? It seems like an impossibility that the “lights” will turn on in the same way without a doubtful, thinking self.
