More quotes by William Stanley Jevons
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
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
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
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
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
By a commodity we shall understand any object, substance, action or service, which can afford pleasure or ward off pain.
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
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
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
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
Capital simply allows us to expend labour in advance.
William Stanley Jevons
A correct theory is the first step towards improvement, by showing what we need and what we might accomplish.
William Stanley Jevons
PLEASURE and pain are undoubtedly the ultimate objects of the calculus of economics. To satisfy our wants to the utmost with the least effort - to procure the greatest amount of what is desirable at the expense of the least that is undesirable - in other words, to maximize pleasure, is the problem of economics.
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
The child which overbalances itself in learning to walk is experimenting on the law of gravity.
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
An isolated man like Alexander Selkirk might feel the benefit of a stock of provisions, tools and other means of facilitating industry, although cut off from traffic, with other men.
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
but, in reality, there is no such thing as an exact science.
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
