The only roads of enquiry there are to think of: one, that it is and that it is not possible for it not to be, this is the path of persuasion (for truth is its companion); the other, that it is not and that it must not be - this I say to you is a path wholly unknowable.
Parmenides

Socrates

Albert Einstein
19.

In other words, the propositions of philosophy are not factual, but linguistic in character - that is, they do not describe the behaviour of physical, or even mental, objects; they express definitions, or the formal consequences of definitions. Accordingly we may say that philosophy is a department of logic. For we will see that the characteristic mark of a purely logical enquiry, is that it is concerned with the formal consequences of our definitions and not with questions of empirical fact.
A.J. Ayer
23.
Political Economy as a branch of science is extremely modern; but the subject with which its enquiries are conversant has in all ages necessarily constituted one of the chief practical interests of mankind.
John Stuart Mill

Touch and away, Jack?’ asked Stephen. ‘Touch and away? Do you not recall that I have important business there? Enquiries of the very first interest?’ To do with our enterprise? To do with this voyage?’ Perhaps not quite directly.
Patrick O'Brian
25.
The human understanding is unquiet; it cannot stop or rest, and still presses onward, but in vain. Therefore it is that we cannot conceive of any end or limit to the world, but always as of necessity it occurs to us that there is something beyond... But he is no less an unskilled and shallow philosopher who seeks causes of that which is most general, than he who in things subordinate and subaltern omits to do so
Francis Bacon
26.
The branches of mathematics are as various as the sciences to which they belong, and each subject of physical enquiry has its appropriate mathematics. In every form of material manifestation, there is a corresponding form of human thought, so that the human mind is as wide in its range of thought as the physical universe in which it thinks.
Benjamin Peirce
27.
Science teaches us, in effect, to submit our reason to the truth and to know and judge of things as they are-that is to say, as they themselves choose to be and not as we would have them to be.
Miguel de Unamuno
