“By the help of God and with His precious assistance, I say that Algebra is a scientific art. The objects with which it deals are absolute numbers and measurable quantities which, though themselves unknown, are related to "things" which are known, whereby the determination of the unknown quantities is possible.”

Omar Khayyám (1048–1131) Persian poet, philosopher, mathematician, and astronomer

Treatise on Demonstration of Problems of Algebra (1070).
Context: By the help of God and with His precious assistance, I say that Algebra is a scientific art. The objects with which it deals are absolute numbers and measurable quantities which, though themselves unknown, are related to "things" which are known, whereby the determination of the unknown quantities is possible. Such a thing is either a quantity or a unique relation, which is only determined by careful examination. What one searches for in the algebraic art are the relations which lead from the known to the unknown, to discover which is the object of Algebra as stated above. The perfection of this art consists in knowledge of the scientific method by which one determines numerical and geometric unknowns.

“The future has several names. For the weak, it is impossible; for the fainthearted, it is unknown; but for the valiant, it is ideal.”

Victor Hugo book Les Misérables

Variant: The future has many names: For the weak, it means the unattainable. For the fearful, it means the unknown. For the courageous, it means opportunity.

“As long as a thing is unknown, it belongs to us in a way that well-known things do not. For we have the opportunity to fill the empty, unknown spaces for ourselves, and in them there is room for imagination and for hope.”

Cameron Dokey (1956) American writer

“Shall we educate ourselves in what is known, and then casting away all we have acquired, turn to ignorance for aid to guide us among the unknown?”

Michael Faraday (1791–1867) English scientist

“The philosophers likewise assume that in Nature there is nothing in vain, so that everything that is not the product of human industry serves a certain purpose, which may be known or unknown to us.”

“I could give here several other ways of tracing and conceiving a series of curved lines, each curve more complex than any preceding one, but I think the best way to group together all such curves and them classify them in order, is by recognizing the fact that all points of those curves which we may call "geometric," that is, those which admit of precise and exact measurement, must bear a definite relation to all points of a straight line, and that this relation must be expressed by a single equation. If this equation contains no term of higher degree than the rectangle of two unknown quantities, or the square of one, the curve belongs to the first and simplest class, which contains only the circle, the parabola, the hyperbola, and the ellipse; but when the equation contains one or more terms of the third or fourth degree in one or both of the two unknown quantities (for it requires two unknown quantities to express the relation between two points) the curve belongs to the second class; and if the equation contains a term of the fifth or sixth degree in either or both of the unknown quantities the curve belongs to the third class, and so on indefinitely.”

“In any given society the Remnant are always so largely an unknown quantity.”

Albert Jay Nock (1870–1945) American journalist

Source: Isaiah's Job (1936), IV
Context: In any given society the Remnant are always so largely an unknown quantity. You do not know, and will never know, more than two things about them. You can be sure of those — dead sure, as our phrase is — but you will never be able to make even a respectable guess at anything else. You do not know, and will never know, who the Remnant are, nor what they are doing or will do. Two things you do know, and no more: First, that they exist; second, that they will find you. Except for these two certainties, working for the Remnant means working in impenetrable darkness; and this, I should say, is just the condition calculated most effectively to pique the interest of any prophet who is properly gifted with the imagination, insight and intellectual curiosity necessary to a successful pursuit of his trade.
