It is clear that economics, if it is to be a science at all, must be a mathematical science.
William Stanley Jevons
Image
In any case I hold that there must arise a science of the development of economic forms and relations.
William Stanley Jevons
Image
My principal work now lies in tracing out the exact nature and conditions of utility. It seems strange indeed that economists have not bestowed more minute attention on a subject which doubtless furnishes the true key to the problems of economics.
William Stanley Jevons
Image
One of the most important axioms is, that as the quantity of any commodity, for instance, plain food, which a man has to consume, increases, so the utility or benefit derived from the last portion used decreases in degree. The decrease in enjoyment between the beginning and the end of a meal may be taken as an example.
William Stanley Jevons
Image
A spade may be made of any size, and if the same number of strokes be made in the hour, the requisite exertion will vary nearly as the cube of the length of the blade.
William Stanley Jevons
Image
Some of the gold possessed by the Romans is doubtless mixed with what we now possess and some small part of it will be handed down as long as the human race exists.

Property is only another name for monopoly.
William Stanley Jevons
Image
There is no such thing as absolute cost of labour it is all a matter of comparison. Every one gets the most which he can for his exertions some can get little or nothing, because they have not sufficient strength, knowledge or ingenuity others get much, because they have, comparatively speaking, a monopoly of certain powers.

Science arises from the discovery of Identity amid Diversity.
William Stanley Jevons
Image
The whole result of continued labour is not often consumed and enjoyed in a moment the result generally lasts for a certain length of time. We must then conceive the capital as being progressively uninvested.
William Stanley Jevons
Image
We shall never have a science of economics unless we learn to discern the operation of law even among the most perplexing complications and apparent interruptions.
William Stanley Jevons
Image
You will perceive that economy, scientifically speaking, is a very contracted science it is in fact a sort of vague mathematics which calculates the causes and effects of man's industry, and shows how it may be best applied.
William Stanley Jevons
Image
The whole value of science consists in the power which it confers upon us of applying to one object the knowledge acquired from like objects and it is only so far, therefore, as we can discover and register resemblances that we can turn our observations to account.
William Stanley Jevons
Image
Repeated reflection and inquiry have led me to the somewhat novel opinion, that value depends entirely upon utility.
William Stanley Jevons
Image
Economists can never be free of from difficulties unless they will distinguish between a theory and the application of a theory.
William Stanley Jevons
Image
Many persons entertain a prejudice against mathematical language, arising out of a confusion between the ideas of a mathematical science and an exact science. ...in reality, there is no such thing as an exact science.
William Stanley Jevons
Image
There are a multitude of allied branches of knowledge connected with mans condition the relation of these to political economy is analogous to the connexion of mechanics, astronomy, optics, sound, heat, and every other branch more or less of physical science, with pure mathematics.

Image
By a commodity we shall understand any object, substance, action or service, which can afford pleasure or ward off pain.
William Stanley Jevons
Image
I feel quite unable to adopt the opinion that the moment goods pass into the possession of the consumer they cease altogether to have the attributes of capital.

One pound invested for five years gives the same result as five pounds invested for one year, the product being five pound years.
