Existence, Proofs of
We know our own existence intuitively and God's existence by demonstration.
Existence is the state of being, or having an actual essence. Mr. Locke says, that we arrive at the knowledge of our own existence by intuition; of the existence of God, by demonstration; of other things, by sensation. As for our own existence, continues he, we perceive it so plainly, that it neither needs, nor is capable of, any proof. I think, I reason, I feel pleasure and pain: can any of these be more evident to me than my own existence? If I doubt of all these things, that very doubt makes me perceive my own existence, and will not suffer me to doubt. If I know I doubt, I have as certain a perception of the thing doubting as of that thought which I call doubt: experience, then, convinces us that we have an intuitive knowledge of our own existence. Maunder.
