A Quote by August Krogh
The theory of the lung as a gland has justified its existence and done excellent service in bringing forward facts, which shall survive any theoretical construction that has been or may hereafter be put upon them.

The fact that Science walks forward on two feet, namely theory and experiment, is nowhere better illustrated than in the two fields for slight contributions to which you have done me the great honour of awarding the the Nobel Prize in Physics for the year 1923. Sometimes it is one foot that is put forward first, sometimes the other, but continuous progress is only made by the use of both-by theorizing and then testing, or by finding new relations in the process of experimenting and then bringing the theoretical foot up and pushing it on beyond, and so on in unending alterations.
Any damage that's been done, you have to fix yourself because it needs fixing and there is nobody else to do the work. Blame may well be justified, but it's not going to move you forward in your life.
All good intellects have repeated, since Bacon's time, that there can be no real knowledge but that which is based on observed facts. This is incontestable, in our present advanced stage; but, if we look back to the primitive stage of human knowledge, we shall see that it must have been otherwise then. If it is true that every theory must be based upon observed facts; it is equally true that facts can not be observed without the guidance of some theory. Without such guidance, our facts would be desultory and fruitless; we could not retain them: for the most part we could not even perceive them.
Observation and theory get on best when they are mixed together, both helping one another in the pursuit of truth. It is a good rule not to put overmuch confidence in a theory until it has been confirmed by observation. I hope I shall not shock the experimental physicists too much if I add that it is also a good rule not to put overmuch confidence in the observational results that are put forward until they have been confirmed by theory.
Poetry and painting have arrived to their perfection in our own country; music is yet but in its nonage [immaturity], a forward Child, which gives hope of what it may be hereafter in England, when the masters of it shall find more Encouragement.
My facts shall be falsehoods to the common sense. I would so state facts that they shall be significant, shall be myths or mythologic. Facts which the mind perceived, thoughts which the body thought - with these I deal.
The standard theory may survive as a part of the ultimate theory, or it may turn out to be fundamentally wrong. In either case, it will have been an important way-station, and the next theory will have to be better.
A theoretical system does not merely state facts which have been observed and that logically deducible relations to other facts which have also been observed.
Generally speaking, geologists seem to have been much more intent on making little worlds of their own, than in examining the crust of that which they inhabit. It would be much more desirable that facts should be placed in the foreground and theories in the distance, than that theories should be brought forward at the expense of facts. So that, in after times, when the speculations of the present day shall have passed away, from a greater accumulation of information, the facts may be readily seized and converted to account.
It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system.
To imagine that "God moves in mysterious ways" is to put up a smokescreen of mystery behind which fantasy may survive in spite of all the facts.
And, as for me, if, by any possibility, there be any as yet undiscovered prime thing in me; if I shall ever deserve any real repute in that small but high hushed world which I might not be unreasonably ambitious of ; if hereafter I shall do anything that, upon the whole, a man might rather have done than to have left undone ; if, at my death, my executors, or more properly my creditors, find any precious MSS. in my desk, then here I prospectively ascribe all the honour and the glory to whaling; for a whale-ship was my Yale College and my Harvard.
Everyone has a set of presuppositions: what gender is, what it's not. And they may not write them out or they may not be in theoretical books published by Routledge, but they have a theory.
No theory ever agrees with all the facts in its domain, yet it is not always the theory that is to blame. Facts are constituted by older ideologies, and a clash between facts and theories may be proof of progress. It is also a first step in our attempt to find the principles implicit in familiar observational notions.
I love fat people. Every fat person says it's not their fault, that they have gland trouble. You know which gland? The saliva gland.
The hypothesis may be put forward, to be tested by the s subsequent investigation, that this development has been in large part a matter of the reciprocal interaction of new factual insights and knowledge on the one hand with changes in the theoretical system on the other.
