Even a statement very close to the periphery can be held true in the face of recalcitrant experience by pleading hallucination or by amending certain statements of the kind called logical laws. Conversely, by the same token, no statement is immune to revision. Revision even of the logical law of the excluded middle has been proposed as a means of simplifying quantum mechanics; and what difference is there in principle between such a shift and the shift whereby Kepler superseded Ptolemy, or Einstein Newton, or Darwin Aristotle?

A seeker after Truth cannot afford to indulge in generalisation. Darwin for the greater part of his book Origin of the Species [sic] has simply massed fact upon fact without any theorising, and only towards the end has formulated his conclusion which, because of the sheer weight of testimony behind it, becomes almost irresistible. Yes I have criticised even Darwin's generalisation as being unwarranted. Science tells us that a proposition may hold good in nine hundred ninety-nine cases and yet fail in the thousandth case and thus be rendered untenable as a universal statement.

When we consider a human work, we believe we know where the "intelligence" which fashioned it comes from; but when a living being is concerned, no one knows or ever knew, neither Darwin nor Epicurus, neither Leibniz nor Aristotle, neither Einstein nor Parmenides. An act of faith is necessary to make us adopt one hypothesis rather than another. Science, which does not accept any credo, or in any case should not, acknowledges its ignorance, its inability to solve this problem which, we are certain, exists and has reality.
Pierre-Paul Grassé
The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
Paul Dirac
The last thirty years of Einstein's life were largely devoted to a search for a so-called unified field theory that would unify James Clerk Maxwell's theory of electromagnetism with the general theory of relativity, Einstein's theory of gravitation. Einstein's attempt was not successful, and with hindsight we can now see that it was misconceived. Not only did Einstein reject quantum mechanics; the scope of his effort was too narrow. ... Nevertheless Einstein's struggle is our struggle today. It is the search for a final theory.

Every one of us knows how painful it is to be called by malicious names, to have his character undermined by false insinuations, to be overreached in a bargain, to be neglected by those who rise in life, to be thrust on one side by those who have stronger wills and stouter hearts. Every one knows, also, the pleasure of receiving a kind look, a warm greeting, a hand held out to help in distress, a difficulty solved, a higher hope revealed for this world or the next. By that pain and by that pleasure let us judge what we should do to others.
