Property is only another name for monopoly.
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
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
What capital I give for the spade merely replaces what the manufacturer had already invested in the expectation that the spade would be needed.
William Stanley Jevons
Image
Over-production is not possible in all branches of industry at once, but it is possible in some as compared to others.
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
Repeated reflection and inquiry have led me to the somewhat novel opinion, that value depends entirely upon utility.

The child which overbalances itself in learning to walk is experimenting on the law of gravity.
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.

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
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
Image
A correct theory is the first step towards improvement, by showing what we need and what we might accomplish.
William Stanley Jevons
Image
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
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

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.

It is clear that economics, if it is to be a science at all, must be a mathematical science.

Logic is not only an exact science, but is the most simple and elementary of all sciences it ought therefore undoubtedly to find some place in every course of education.

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
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.

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.
