The ethical ideas on which civilization rests have been wandering about the world, poverty-stricken and homeless. No theory of the universe has been advanced which can give them solid foundation; in fact not one has made its appearance which can claim for itself solidity and inner consistency. The age of philosophical dogmatism had come to an end, and after that nothing was recognized as truth except the science which described reality. Complete theories of the universe no longer appeared as fixed stars; they were regarded as resting on hypothesis, and ranked no higher than comets.

Writers may be classified as meteors, planets, and fixed stars. A meteor makes a striking effect for a moment. You look up and cry “There!” and it is gone forever. Planets and wandering stars last a much longer time. They often outshine the fixed stars and are confounded by them by the inexperienced; but this only because they are near. It is not long before they must yield their place; nay, the light they give is reflected only, and the sphere of their influence is confined to their orbit — their contemporaries. Their path is one of change and movement, and with the circuit of a few years their tale is told. Fixed stars are the only ones that are constant; their position in the firmament is secure; they shine with a light of their own; their effect today is the same as it was yesterday, because, having no parallax, their appearance does not alter with a difference in our standpoint. They belong not to one system, one nation only, but to the universe. And just because they are so very far away, it is usually many years before their light is visible to the inhabitants of this earth.

 

Arthur Schopenhauer

 

Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome. And human beings evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other, yet to be discovered. [...] Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us for a style of argument that they themselves favor). In science, “fact” can only mean “confirmed to such a degree that it would be perverse to withhold provisional assent.” I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

This is what fascinates Shaw: this enormous force that ignores our human preferences, our logic and intellect. It fascinates him because to be suddenly gripped by it is to see that human beings are not the accidental products of a mechanical universe — that they are not 'alone'. As social animals, we live in a narrow but apparently logical world with a well-defined identity and position. But man is the satellite of a double-star; there is also an inner-world that seems to have a completely different set of laws from the rational universe. And in fact, if we judge this 'rational universe' by its own laws, we see that it is not self-complete and self-explanatory; space must end somewhere, time must have a stop; but the alternative propositions sound equally 'logical': space is infinite; time has neither beginning nor end. The answer to these paradoxes must be that the outer universe is not self-complete; it is only half a universe. The inner world is the other half. But at present we know very little about this inner world. It is only within the present century that its existence has been clearly recognized by psychology.

If there is no point in the universe that we discover by the methods of science, there is a point that we can give the universe by the way we live, by loving each other, by discovering things about nature, by creating works of art. And that—in a way, although we are not the stars in a cosmic drama, if the only drama we're starring in is one that we are making up as we go along, it is not entirely ignoble that faced with this unloving, impersonal universe we make a little island of warmth and love and science and art for ourselves. That's not an entirely despicable role for us to play.

 

Steven Weinberg

 

One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He used very advanced mathematics in constructing the universe. Our feeble attempts at mathematics enable us to understand a bit of the universe, and as we proceed to develop higher and higher mathematics we can hope to understand the universe better.
