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
The point of equilibrium will be known by the criterion that an infinitely small amount of commodity exchanged in addition, at the same rate, will bring neither gain nor loss of utility.
William Stanley Jevons
Image
One of the first and most difficult steps in a science is to conceive clearly the nature of the magnitudes about which we are arguing.
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.
William Stanley Jevons
Image
Property is only another name for monopoly.
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
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
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
Image
The theory which follows is entirely based on a calculus of pleasure and pain and the object of economics is to maximize happiness by purchasing pleasure, as it were, at the lowest cost of pain.
William Stanley Jevons
Image
The difficulties of economics are mainly the difficulties of conceiving clearly and fully the conditions of utility.
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.
William Stanley Jevons
Image
Capital simply allows us to expend labour in advance.
William Stanley Jevons
Image
Science arises from the discovery of Identity amid Diversity.
William Stanley Jevons
Image
I consider that interest is determined by the increment of produce which it enables a labourer to obtain, and is altogether independent of the total return which he receives for this labour.
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
It is clear that Economics, if it is to be a science at all, must be a mathematical science ... simply because it deals with quantities... As the complete theory of almost every other science involves the use of calculus, so we cannot have a true theory of Economics without its aid.

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.

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
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.

In matters of philosophy and science authority has ever been the great opponent of truth. A despotic calm is usually the triumph of error. In the republic of the sciences sedition and even anarchy are beneficial in the long run to the greatest happiness of the greatest number.
