PhilosophyQuotes:

"...no philosophical opinion, however ancient, however generally received, ought to rest upon authority. There is no presumption in requiring evidence for it, or in regulating our belief by the evidence we can find."

"An object, in being perceived, does not act at all."

"I see as little reason...to believe that in perception the mind acts upon the object. To perceive an object is one thing, to act upon it is another; nor is the last at all included in the first."

-Thomas Reid (1710-1796), Essays on the Intellectual Powers of Man (1785)
