Theory Purpose
“we must avoid postulating a new element for each new phenomenon. But an equally serious mistake is to admit into the theory only those elements which can now be observed. For the purpose of a theory is not only to correlate the results of observations that we already know how to make, but also to suggest the need for new kinds of observations and to predict their results. In fact, the better a theory is able to suggest the need for new kinds of observations and to predict their results correctly, the more confidence we have that this theory is likely to be good representation of the actual properties of matter and not simply an empirical system especially chosen in such a way as to correlate a group of already known facts.”

True Ideas
“True ideas are those that we can assimilate, validate, corroborate, and verify. False ideas are those that we can not. That is the practical difference it makes to us to have true ideas; that, therefore, is the meaning of truth, for it is all that truth is known-as. This thesis is what I have to defend. The truth of an idea is not a stagnant property inherent in it. Truth happens to an idea. It becomes true, is made true by events. Its verity is in fact an event, a process: the process namely of its verifying itself, its verification. Its validity is the process of its validation.”

Show_Them
“We have a lot of customers, and we have a lot of research into our installed base. We also watch industry trends pretty carefully. But in the end, for something this complicated, it's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them. That's why a lot of people at Apple get paid a lot of money, because they're supposed to be on top of these things.”

Physical Causes
“Some physical causes are recognized by all; others, by only very few people; indeed, many things exist naturally, but from causes hitherto known to no man. And of the causes, which we know, there are some whose kind and nature we all usually understand, and others whose kind or indirect cause are understood by very few people, or by nobody.”

Unknown Unknowns
“...There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns — the ones we don't know we don't know... It is the latter category that tends to be the difficult ones.”

Average versus First Class Productivity
“That there is a difference between the average and the first class man is known to all employers, but that the first class man can do in most cases from two to four times as much is known to few, and is fully realized only by those who have made a thorough and scientific study of the possibilities of men.”
