Some writers maintain arithmetic to be only the only sure guide in political economy; for my part, I see so many detestable systems built upon arithmetical statements, that I am rather inclined to regard that science as the instrument of national calamity.

The desire to economize time and mental effort in arithmetical computations, and to eliminate human liability to error is probably as old as the science of arithmetic itself.

 

Howard H. Aiken

 

You ask me what I would “substitute for the Bible as a moral guide.” I know that many people regard the Bible as the only moral guide and believe that in that book only can be found the true and perfect standard of morality. There are many good precepts, many wise sayings and many good regulations and laws in the Bible, and these are mingled with bad precepts, with foolish sayings, with absurd rules and cruel laws.
But we must remember that the Bible is a collection of many books written centuries apart, and that it in part represents the growth and tells in part the history of a people. We must also remember that the writers treat of many subjects. Many of these writers have nothing to say about right or wrong, about vice or virtue.

 

Robert G. Ingersoll

 

Art is naturally concerned with man in his existential aspect, not in his scientific aspect. For the scientist, questions about man's stature and significance, suffering and power, are not really scientific questions; consequently he is inclined to regard art as an inferior recreation. Unfortunately, the artist has come to accept the scientist's view of himself. The result, I contend, is that art in the twentieth century — literary art in particular — has ceased to take itself seriously as the primary instrument of existential philosophy. It has ceased to regard itself as an instrument for probing questions of human significance. Art is the science of human destiny. Science is the attempt to discern the order that underlies the chaos of nature; art is the attempt to discern the order that underlies the chaos of man. At its best, it evokes unifying emotions; it makes the reader see the world momentarily as a unity.

Suppose I think, after doing my accounts, that I have a large balance at the bank. And suppose you want to find out whether this belief of mine is “wishful thinking.” You can never come to any conclusion by examining my psychological condition. Your only chance of finding out is to sit down and work through the sum yourself. When you have checked my figures, then, and then only, will you know whether I have that balance or not. If you find my arithmetic correct, then no amount of vapouring about my psychological condition can be anything but a waste of time. If you find my arithmetic wrong, then it may be relevant to explain psychologically how I came to be so bad at my arithmetic, and the doctrine of the concealed wish will become relevant—but only after you have yourself done the sum and discovered me to be wrong on purely arithmetical grounds. It is the same with all thinking and all systems of thought. If you try to find out which are tainted by speculating about the wishes of the thinkers, you are merely making a fool of yourself. You must first find out on purely logical grounds which of them do, in fact, break down as arguments. Afterwards, if you like, go on and discover the psychological causes of the error.

 

C. S. Lewis

 

All relations are either qualitative or quantitative. Qualitative relations can be considered by themselves without regard to quantity. The algebra of such enquiries may be called logical algebra, of which a fine example is given by Boole.
Quantitative relations may also be considered by themselves without regard to quality. They belong to arithmetic, and the corresponding algebra is the common or arithmetical algebra.
In all other algebras both relations must be combined, and the algebra must conform to the character of the relations.
