“Never mind what two tons refers to. What is it? How has it entered in so definite a way into our exprerience? Two tons is the reading of the pointer when the elephant was placed on a weighing machine. Let us pass on. … And so we see that the poetry fades out of the problem, and by the time the serious application of exact science begins we are left only with pointer readings.”

“We speak of the matter [of this science] in the sense of its being what the science is about. This is called by some the subject of the science, but more properly it should be called its object, just as we say of a virtue that what it is about is its object, not its subject. As for the object of the science in this sense, we have indicated above that this science is about the transcendentals. And it was shown to be about the highest causes. But there are various opinions about which of these ought to be considered its proper object or subject. Therefor, we inquire about the first. Is the proper subject of metaphysics being as being, as Avicenna claims, or God and the Intelligences, as the Commentator, Averroes, assumes.”
loquimur de materia "circa quam" est scientia, quae dicitur a quibusdam subiectum scientiae, uel magis proprie obiectum, sicut et illud circa quod est uirtus dicitur obiectum uirtutis proprie, non subiectum. De isto autem obiecto huius scientiae ostensum est prius quod haec scientia est circa transcendentia; ostensum est autem quod est circa altissimas causas. Quod autem istorum debeat poni proprium eius obiectum, uariae sunt opiniones. Ideo de hoc quaeritur primo utrum proprium subiectum metaphysicae sit ens in quantum ens (sicut posuit Auicenna) uel Deus et Intelligentiae (sicut posuit Commentator Auerroes.)

“Information retrieval consists of four main stages: Identifying the exact subject of the search; Locating this subject in a guide which refers the searcher to one or more documents; Locating the documents; Locating the required information in the documents.”

“Well, I will say this. And this is the main thing to remember. Macroeconomics -- even with all of our computers and with all of our information -- is not an exact science and is incapable of being an exact science. It can be better or it can be worse, but there isn't guaranteed predictability in these matters.”

“The world does not consist of subjects and objects, the “subject” and the “object” are metaphysical abstractions of the single and indivisible Wholeness. Man’s finite knowledge separates the Whole into parts and studies fragmentarily the beings. The Wholeness is manifested in multiple forms and each form encapsulates the Wholeness.”

“Politics is not an exact science.”

Otto von Bismarck (1815–1898) German statesman, Chancellor of Germany

Die Politik ist keine exakte Wissenschaft.
Speech to Prussian upper house (18 December 1863)
Politics is not a science, as the professors are apt to suppose. It is an art.

1860s
Variant: Die Politik ist keine Wissenschaft, wie viele der Herren Proffessoren sich einbilden, sondern eine Kunst.
