Philosophy, in spite of all its tiresome features, is not a luxury but a necessity, because we always have to use it when things get difficult. - Mary Midgley

But my present point is a much wider one. What we need, in order to feel at home in the world, is certainly not a belief that it was made for us. We are at home in this world because we were made for it. we have develped here, on this planet, and are adapted to live here. Our emotional constitution is part of that adaptation. We are not fit to live anywhere else (the possibility, such as it is, of surviving briefly, and at ruinous expense in space-craft and the like is just parasitical; it depends on extending the conditions we are used to into a few bizairre corners, not on our being able to live in other conditions.

The future will not "be with" anybody in the sense of falling to them as a conquest. The need for many different methods is not going to go away, dissolved in a quasi-physical heaven where all serious work is quantitative...Quantification, like surgery, is an excellent thing in the right place, but a very bad topic for obsession. Unless you know just what you are counting--unless you are sure that the things counted are standard units--and unless you understand what is proved by results of your counting, quantifying provide you only with the outward show of science, a mirage, never the oasis.

In fact, the whole idea of illusion seems to make sense only if we accept the reality of the illusory experience as an experience and question only what it seems to be telling us about the outside world. Optical illusions do really hapen. What they can’t do is provide accurate measurements of the outside world. The idea of having, so to speak, two successive layers of illusion here is unworkable.
