“No man is a devil in his own mind.”

“Man can hardly even recognize the devils of his own creation.”

“Man provides his own goods and his own evils, neither God nor the Devil has anything to do with it.”

“He saw a lawyer killing a viper
On a dunghill hard, by his own stable
And the devil smiled, for it put him in mind Of
Cain and his brother, Abel.”

“A man is likely to mind his own business when it is worth minding. When it is not, he takes his mind off his own meaningless affairs by minding other people's business.”

“Let every man mind his own business.”

“I think the devil doesn't exist, but man has created him, he has created him in his own image and likeness.”

“The fallen angels took full responsibility. I don't think anyone tempted the devil to rebel in the first place. He just made up his own mind.”

“The mind is everything. It is in the mind alone that one feels pure and impure. A man, first of all, must make his own mind guilty and then alone can he see another man's guilt.”

“It is man's own fault, it is from want of use, if his mind grows torpid in old age.”
