If I have no beliefs. No faith. Then I only have thoughts. Thoughts manufactured within a vessel of questionable integrity.

My understanding of reality is solely dependent on my minds interpretation of the world through external stimuli.
However.
I don’t quite trust my minds interpretations.
Sometimes I’m convinced that it has no idea what it’s doing and that it’s just making up **** as it goes along.
So.
Before you ask me if I love you.
You should know that I’m still not entirely convinced you’re not who or what you say you are.
You could just be a figment of my imagination.
Neither one of us can prove our existence to the other.
So.
What do I say?
