More quotes by William Stanley Jevons
There are many portions of economical doctrine which appear to me as scientific in form as they are consonant with facts.
William Stanley Jevons
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
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
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
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
A correct theory is the first step towards improvement, by showing what we need and what we might accomplish.
William Stanley Jevons
There are a multitude of allied branches of knowledge connected with mans condition the relation of these to political economy is analogous to the connexion of mechanics, astronomy, optics, sound, heat, and every other branch more or less of physical science, with pure mathematics.
William Stanley Jevons
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
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
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
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
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 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
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
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
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
but, in reality, there is no such thing as an exact science.
William Stanley Jevons
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
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
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
