So I have to ask myself whether I have the power to bringit about that I, who now exist, will still exist a minute fromnow. For since I am nothing but a thinking thing—or anywaythat is the only part of me that I am now concerned with—ifI had such a power I would undoubtedly be aware of it
This really stood out to me. If the only thing we can for sure do is think then that is not enough to keep ourselves existing.
