You couldn't put me in a social group setting. I'm probably a terrible anarchist deep down.

There is nothing deep down inside us except what we have put there ourselves.

Deep down, I'm pretty superficial.

Deep down, there is in the substance of the cosmos a primordial disposition, sui generis, for self-arrangement and self-involution.

Deep down, I happen to be very shallow.

Deep down, I'm just a West Virginia hillbilly.
