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.

More quotes by William Stanley Jevons

Image
In short, I do not write for mathematicians, nor as a mathematician, but as an economist wishing to convince other economists that their science can only be satisfactorily treated on an explicitly mathematical basis.
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
Logic should no longer be considered an elegant and learned accomplishment it should take its place as an indispensable study for every well-informed person.
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

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
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
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
The child which overbalances itself in learning to walk is experimenting on the law of gravity.
William Stanley Jevons
Image
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
Image
Ina regular and constant employment the greatest result will always be gained by such a rate as allows a workman each day,or each week at the most, to recover all fatigue and recommence with an undiminished store of energy.
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
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
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
but, in reality, there is no such thing as an exact science.
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
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
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
Image
One pound invested for five years gives the same result as five pounds invested for one year, the product being five pound years.

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.
