“The Common Sense, is that which judges of things offered to it by the other senses. The ancient speculators have concluded that that part of man which constitutes his judgment is caused by a central organ to which the other five senses refer everything by means of impressibility; and to this centre they have given the name Common Sense. And they say that this Sense is situated in the centre of the head between Sensation and Memory. And this name of Common Sense is given to it solely because it is the common judge of all the other five senses i. e. Seeing, Hearing, Touch, Taste and Smell. This Common Sense is acted upon by means of Sensation which is placed as a medium between it and the senses. Sensation is acted upon by means of the images of things presented to it by the external instruments, that is to say the senses which are the medium between external things and Sensation. In the same way the senses are acted upon by objects. Surrounding things transmit their images to the senses and the senses transfer them to the Sensation. Sensation sends them to the Common Sense, and by it they are stamped upon the memory and are there more or less retained according to the importance or force of the impression.”

“Using, as an excuse, others’ failure of common sense is in itself a failure of common sense.”

“Common sense and a sense of humor are the same thing, moving at different speeds. A sense of humor is just common sense, dancing.”

“Most psychologists agree at least some of our analytical ability is innate; however, most also agree common sense is not innate but derived from learned experiences; since common sense which I refer to as reasoned judgment requires analysis, then reasoned judgment must be partly innate.”

“It is a thousand times better to have common sense without education than to have education without common sense.”

“Our best theories are not only truer than common sense, they make more sense than common sense…”

“Common sense and a sense of humour are the same thing, moving at different speeds. A sense of humour is just common sense, dancing. Those who lack humour are without judgement and should be trusted with nothing.”

“There are two things in the world that can never get on together—religion and common sense. Religion deals with the next life, common sense with this; religion points to the sky, common sense to the earth; religion is all imagination, common sense all reason; religion deals with what nobody can understand, common sense with what everybody can understand; religion gives us no return for our investments but flash notes on the bank of expectation, common sense gives us good interest and full security for our capital. They are as opposite as two things can possibly be, and they are always at strife. Religion is always trying to fill the world with delusions, and common sense is always trying to drive them away. Religion says Live for the next world, and common sense says Live for this.”

“A sense of humor is just common sense dancing.”

“That seems to us to be the common sense of the matter; and common sense often makes good law.”
