“For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable – what then?”
― George Orwell, 1984

“Sometimes people hold a core belief that is very strong. When they are
presented with evidence that works against that belief, the new
evidence cannot be accepted. It would create a feeling that is
extremely uncomfortable, called cognitive dissonance. And because it
is so important to protect the core belief, they will rationalize,
ignore and even deny anything that doesn't fit in with the core belief.”
― Frantz Fanon, Black Skin, White Masks

“The human mind is not a terribly logical or consistent place.”
― Jim Butcher, Turn Coat

“Mistakes are, after all, the foundations of truth, and if a man does not know what a thing is, it is at least an increase in knowledge if he knows what it is not. ”
― Carl G. Jung
