If all the thought which had been expended on the construction of engines of agony and death — the modes of aggression and defence, the raising of armies, and the acquirement of those arts of tyranny and falsehood without which mixed multitudes could neither be led nor governed — had been employed to promote the true welfare and extend the real empire of man, how different would have been the present situation of human society! how different the state of knowledge in physical and moral science, upon which the power and happiness of mankind essentially depend!

Further, it will not be amiss to distinguish the three kinds and, as it were, grades of ambition in mankind. The first is of those who desire to extend their own power in their native country, a vulgar and degenerate kind. The second is of those who labor to extend the power and dominion of their country among men. This certainly has more dignity, though not less covetousness. But if a man endeavor to establish and extend the power and dominion of the human race itself over the universe, his ambition (if ambition it can be called) is without doubt both a more wholesome and a more noble thing than the other two. Now the empire of man over things depends wholly on the arts and sciences. For we cannot command nature except by obeying her.

 

Francis Bacon

 

Fame, power, and gold, are loved for their own sakes — are worshipped with a blind, habitual idolatry. The pageantry of empire, and the fame of irresistible might, are contemplated by the possessor with unmeaning complacency, without a retrospect to the properties which first made him consider them of value. It is from the cultivation of the most contemptible properties of human nature that discord and torpor and indifference, by which the moral universe is disordered, essentially depend. So long as these are the ties by which human society is connected, let it not be admitted that they are fragile.

Among the strange things of this world, nothing seems more strange than that men pursuing happiness should knowingly quit the right and take a wrong road, and frequently do what their judgments neither approve nor prefer. Yet so is the fact; and this fact points strongly to the necessity of our being healed, or restored, or regenerated by a power more energetic than any of those which properly belong to the human mind.
We perceive that a great breach has been made in the moral and physical systems by the introduction of moral and physical evil; how or why, we know not; so, however, it is, and it certainly seems proper that this breach should be closed and order restored. For this purpose only one adequate plan has ever appeared in the world, and that is the Christian dispensation. In this plan I have full faith. Man, in his present state, appears to be a degraded creature; his best gold is mixed with dross, and his best motives are very far from being pure and free from earth and impurity.

I just want to explain what I mean when I say that we should try to hold on to physical reality.
We are ... all aware of the situation regarding what will turn out to be the basic foundational concepts in physics: the point-mass or the particle is surely not among them; the field, in the Faraday-Maxwell sense, might be, but not with certainty. But that which we conceive as existing ("real") should somehow be localized in time and space. That is, the real in one part of space, A, should (in theory) somehow "exist" independently of that which is thought of as real in another part of space, B. If a physical system stretches over A and B, then what is present in B should somehow have an existence independent of what is present in A. What is actually present in B should thus not depend the type of measurement carried out in the part of space A; it should also be independent of whether or not a measurement is made in A.
If one adheres to this program, then one can hardly view the quantum-theoretical description as a complete representation of the physically real. If one attempts, nevertheless, so to view it, then one must assume that the physically real in B undergoes a sudden change because of a measurement in A. My physical instincts bristle at that suggestion.
However, if one renounces the assumption that what is present in different parts of space has an independent, real existence, then I don't see at all what physics is supposed to be describing. For what is thought to be a "system" is after all, just conventional, and I do not see how one is supposed to divide up the world objectively so that one can make statements about parts.

 

Albert Einstein

 

While it is true that science cannot decide questions of value, that is because they cannot be intellectually decided at all, and lie outside the realm of truth and falsehood. Whatever knowledge is attainable, must be attained by scientific methods; and what science cannot discover, mankind cannot know.
