Provided they are substantiated by hard evidence, not hunches, generalizations are not incorrect. Science relies on the ability to generalize to the larger population observations drawn from a representative sample. People make prudent decisions in their daily lives based on probabilities and generalities. That one chooses not to live in a particular crime-riddled county or country in no way implies that one considers all individual residents there to be criminals, only that a sensible determination has been made, based on statistically significant data, as to where scarce and precious resources-one's life and property-are best invested.

The Nobel Prize confers on an individual an authority which in economics no man ought to possess.
This does not matter in the natural sciences. Here the influence exercised by an individual is chiefly an influence on his fellow experts; and they will soon cut him down to size if he exceeds his competence.
But the influence of the economist that mainly matters is an influence over laymen: politicians, journalists, civil servants and the public generally.
There is no reason why a man who has made a distinctive contribution to economic science should be omnicompetent on all problems of society - as the press tends to treat him till in the end he may himself be persuaded to believe.
Friedrich Hayek
Intelligence, then, is the ability to attain goals in the face of obstacles by means of decisions based on rational (truth-obeying) rules. The computer scientists Allen Newell and Herbert Simon fleshed this idea out further by noting that intelligence consists of specifying a goal, assessing the current situation to see how it differs from the goal, and applying a set of operations that reduce the difference. Perhaps reassuringly, by this definition human beings, not just aliens, are intelligent. We have desires, and we pursue them using beliefs, which, when all goes well, are at least approximately or probabilistically true.
Steven Pinker
There is a positive force, meaning constructive, and a negative force, meaning negative and destructive. They create and complement the entire reality in general and particular through their harsh and perpetual war with one another. As we have said above, the negative force appears at the end of every political phase, elevating it to a better state, and thus the phases follow one another until they reach their ultimate perfection (...) In addition, being a social creature, the individual development is not enough. Rather, one's ultimate perfection depends on the development of all the members of society.
Yehuda Ashlag
That the uneducated and the ill-educated should think the hypothesis that all races of beings, man inclusive, may in process of time have been evolved from the simplest monad, a ludicrous one, is not to be wondered at. But for the physiologist, who knows that every individual being is so evolved-who knows, further, that in their earliest condition the germs of all plants and animals whatever are so similar, "that there is no appreciable distinction amongst them, which would enable it to be determined whether a particular molecule is the germ of a Conferva or of an Oak, of a Zoophyte or of a Man";-for him to make a difficulty of the matter is inexcusable.
Herbert Spencer
The best educators are the ones that inspire their students. That inspiration comes from a passion that teachers have for the subject they're teaching. Most commonly, that person spent their lives studying that subject, and they bring an infectious enthusiasm to the audience. I think many people have that enthusiasm, but they are prevented from being teachers because they didn't go through the teacher mill. Now you have teachers who have been through the teacher mill, yet they have no capacity to inspire anyone at all. It's the inspired student that continues to learn on their own. That's what separates the real achievers in the world from those who pedal along, finishing assignments.
