In Texas, years ago, almost all of the oil came from surface operations. Then someone got the idea that there were greater sources of supply deeper down. A well was drilled five thousand feet deep. The result? A gusher. Too many of us operate on the surface. We never go deep enough to find supernatural resources. The result is, we never operate at our best. More time and investment is involved to go deep but a gusher will pay off.
The ideas of a time are like the clothes of a season: they are as arbitrary, as much imposed by some superior will which is seldom explicit. They are utilitarian and political, the instruments of smooth-running government.
Concepts, like individuals, have their histories and are just as incapable of withstanding the ravages of time as are individuals. But in and through all this they retain a kind of homesickness for the scenes of their childhood.
Not just in commerce but in the world of ideas too our age is putting on a veritable clearance sale. Everything can be had so dirt cheap that one begins to wander whether in the end anyone will want to make a bid.
The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist.
If you have the same ideas as everybody else but have them one week earlier than everyone else then you will be hailed as a visionary. But if you have them five years earlier you will be named a lunatic.
It is not always by plugging away at a difficulty and sticking to it that one overcomes it; often it is by working on the one next to it. Some things and some people have to be approached obliquely, at an angle.
