Perception Quotes

“Faculty Psychology is getting to be respectable again after centuries of hanging around with phrenologists and other dubious types. By faculty psychology I mean, roughly, the view that many fundamentally different kinds of psychological mechanisms must be postulated in order to explain the facts of mental life. Faculty psychology takes seriously the apparent heterogeneity of the mental and is impressed by such prima facie differences as between, say, sensation and perception, volition and cognition, learning and remembering, or language and thought.”

“The most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.”

“What, then, is the basic difference between today's computer and an intelligent being? It is that the computer can be made to seebut not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern--a capacity essential to perception and intelligence.”

“The big difference is, as a man, I can go to a bar at two in the morning and people will be like "He's just a fun guy! That's cool that he can balance all these things." But if you see a person that you know who has two young kids and is a mom, there's no way those perceptions are the same. It's like "Oh, there must be a problem." That's usually what women face.”

“The deep secret of the brain is that not only the spinal cord but the entire central nervous system works this way: internally generated activity is modulated by sensory input. In this view, the difference between being awake and being asleep is merely that the data coming in from the eyes anchors the perception.”

“It happens to everyone as they grow up. You find out who you are and what you want, and then you realize that people you've known forever don't see things the way you do. So you keep the wonderful memories, but find yourself moving on.”

“In every country where man is free to think and to speak, difference of opinion will arise from difference of perception, and the imperfection of reason; but these differences, when permitted, as in this happy country, to purify themselves by free discussion, are but as passing clouds overspreading our land transiently, and leaving our horizon more bright and serene.”
