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
All classes of society are trade unionists at heart, and differ chiefly in the boldness, ability, and secrecy with which they pursue their respective interests.
William Stanley Jevons

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.
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 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
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.
William Stanley Jevons

but, in reality, there is no such thing as an exact science.
William Stanley Jevons
Image
There are many portions of economical doctrine which appear to me as scientific in form as they are consonant with facts.
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
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
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
Image
Repeated reflection and inquiry have led me to the somewhat novel opinion, that value depends entirely upon utility.
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.
