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.

More quotes by William Stanley Jevons
Economists can never be free of from difficulties unless they will distinguish between a theory and the application of a theory.
William Stanley Jevons
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
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.
William Stanley Jevons
Among minor alterations, I may mention the substitution for the name political economy of the single convenient term economics. I cannot help thinking that it would be well to discard, as quickly as possible, the old troublesome double-worded name of our science.
William Stanley Jevons
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
As a general rule, it is foolish to do just what other people are doing, because there are almost sure to be too many people doing the same thing.
William Stanley Jevons
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
As there are so many who talk prose without knowing it, or, again, who syllogize without having the least idea what a syllogism is, so economists have long been mathematicians without being aware of the fact.
William Stanley Jevons
One pound invested for five years gives the same result as five pounds invested for one year, the product being five pound years.
William Stanley Jevons
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
It is clear that economics, if it is to be a science at all, must be a mathematical science.
William Stanley Jevons
There are many portions of economical doctrine which appear to me as scientific in form as they are consonant with facts.
William Stanley Jevons
Labour once spent has no influence on the future value of any article it isgone and lost for ever. In commerce bygones are forever bygones and we are alwaysstarting clearat each moment, judging the values of things with a view to future utility.
William Stanley Jevons
I protest against deference to any man, whether John Stuart Mill, or Adam Smith, or Aristotle, being allowed to check inquiry. Our science has become far too much a stagnant one, in which opinions rather than experience and reason are appealed to.
William Stanley Jevons
Fertility of imagination and abundance of guesses at truth are among the first requisites of discovery but the erroneous guesses must almost of necessity be many times as numerous as those which prove well founded.
William Stanley Jevons
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.
William Stanley Jevons
In any case I hold that there must arise a science of the development of economic forms and relations.
William Stanley Jevons
Repeated reflection and inquiry have led me to the somewhat novel opinion, that value depends entirely upon utility.
William Stanley Jevons
By a commodity we shall understand any object, substance, action or service, which can afford pleasure or ward off pain.
William Stanley Jevons
we often observe that there is abundance of capital to be had at low rates of interest, while there are also large numbers of artisans starving for want of employment.
William Stanley Jevons
