Thomas Reid

"The rules of navigation never navigated a ship. The rules of architecture never built a house."

"There is no greater impediment to the advancement of knowledge than the ambiguity of words."

"Every indication of wisdom, taken from the effect, is equally an indication of power to execute what wisdom planned."

"And, if we have any evidence that the wisdom which formed the plan is in the man, we have the very same evidence, that the power which executed it is in him also."
