“The human mind may perceive truth only through thinking, as is clear from Augustine.”

“The truth can be perceived only through thinking, as is proven by Augustine.”

“None of us is fully able to perceive the truth that shines through another person’s window, nor the falsehood that we may perceive as truth. Thus, we can easily mistake another’s good for evil, and our own evil for good.”

“Whilst part of what we perceive comes through our senses from the object before us, another part (and it may be the larger part) always comes out of our own mind.”

“The human mind is so limited it can only build an arbitrary heaven — and usually the physical comforts they endow it with are naively the kind that can be perceived as we humans perceive — nothing more. No: perhaps I will awake to find myself burning in hell. I think not. I think I will be snuffed out. Black is sleep; black is a fainting spell; and black is death, with no light, no waking.”

“By doubting we come to enquiry, and through enquiry we perceive truth.”
