Does life in some way make use of the potentiality for vast quantum superpositions, as would be required for serious quantum computation? How important are the quantum aspects of DNA molecules? Are cellular microtubules performing some essential quantum roles? Are the subtleties of quantum field theory important to biology? Shall we gain needed insights from the study of quantum toy models? Do we really need to move forward to radical new theories of physical reality, as I myself believe, before the more subtle issues of biology - most importantly conscious mentality - can be understood in physical terms? How relevant, indeed, is our present lack of understanding of physics at the quantum/classical boundary? Or is consciousness really "no big deal,” as has sometimes been expressed? It would be too optimistic to expect to find definitive answers to all these questions, at our present state of knowledge, but there is much scope for healthy debate...

Mathematics have a triple aim. They must furnish an instrument for the study of nature. But that is not all: they have a philosophic aim and, I dare maintain, an esthetic aim. They must aid the philosopher to fathom the notions of number, of space, of time. And above all, their adepts find therein delights analogous to those given by painting and music. They admire the delicate harmony of numbers and forms; they marvel when a new discovery opens to them an unexpected perspective; and has not the joy they thus feel the esthetic character, even though the senses take no part therein? Only a privileged few are called to enjoy it fully, it is true, but is not this the case for all the noblest arts?
This is why I do not hesitate to say that mathematics deserve to be cultivated for their own sake, and the theories inapplicable to physics as well as the others. Even if the physical aim and the esthetic aim were not united, we ought not to sacrifice either.
Henri Poincaré
For, strange as the statement will appear at first sight, modern metaphysics, and to a large extent modern physical science, have been groping for centuries blindly after knowledge which occult philosophy has enjoyed in full measure all the while. Owing to a train of fortunate circumstances, I have come to know that this is the case; I have come into some contact with persons who are heirs of a greater knowledge concerning the mysteries of Nature and humanity than modern culture has yet evolved; and my present wish is to sketch the outlines of this knowledge, to record with exactitude the experimental proofs I have obtained that occult science invest its adepts with a control of natural forces superior to that enjoyed by physicists of the ordinary type, and the grounds there are for bestowing the most respectful consideration on the theories entertained by occult science concerning the constitution and destinies of the human soul.
Alfred Percy Sinnett
That is to say that every single book will be magnetized, will be ordered under complicated mathematical clusters, by related subjects, and semantic markers. You will state your questions, or the subject you are interested in, and the computer will find the books for you. Instataneous retrieval brings with it enormous changes in our relation to the history of a subject, because there is a cut-off point in all these systems beond which the previous books are no longer relevant. They have been adequately subsumed in the later ones. You have a completely different way of organsing knowledge-an immensely efficient and in many ways powerfully logical way, but which blocks the essential motion of the hand reaching along a shelf and stumbling on what it did not know was there. When these great knowledge and data-banks, as they are called, are operative there will come a whole change in the way the human mind and eye live with books.
George Steiner
No one, who knows what the difficulties are, now believes that the crisis of physics is likely to be resolved by any simple trick or modification of existing theories. Something radical is needed, and it will have to go far wider than physics. A new world outlook is being forged, but much experiment and argument will be needed before it can take a definitive form. It must be coherent, it must include and illuminate the new knowledge of fundamental particles and their complex fields, it must resolve the paradoxes of wave and particle, it must make the world inside the atom and the wide spaces of the universe equally intelligible. It must have a different dimension from all previous world views, and include in itself an explanation of development and the origin of new things. In this it will fall naturally in line with the converging tendencies of the biological and social sciences in which a regular pattern blends with their evolutionary history.
John Desmond Bernal
The social sciences building at the University of Chicago indeed still bears since it was built 40 years ago on its outside an inscription taken from the famous physicist Lord Kelvin: "When you cannot measure, your knowledge is meager and unsatisfactory." I will admit that that may be true, but it is certainly not scientific to insist on measurement where you don't know what your measurements mean. There are cases where measurements are not relevant. What has done much damage to microeconomics is striving for a pseudo-exactness by imitating methods of the physical sciences which have to deal with what are fundamentally much more simple phenomena. And the assumption that it is possible to ascertain all the relevant particular facts still completely dominates the alternative methods of dealing with our constitutional ignorance, which economists have tried to overcome. This of course, is what has come to be called macroeconomics as distinct from microeconomics.
Friedrich Hayek
