Can you be sure of anything at all?

Cogito, ergo sum

Can you be sure of anything at all?

Imagine you're in a room with a broken clock. You can't tell what time it is, but you know you're looking at a clock.

Even if you can't tell the time, the fact that you can see the clock means you exist. You think, therefore you are. (Cogito, ergo sum)

Example

You see the clock, you know it's broken, you know it's still there, you know you're there.

Remember this

Just by thinking, you're proving you exist.
