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.

More quotes by William Stanley Jevons
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.
William Stanley Jevons
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
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
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
The difficulties of economics are mainly the difficulties of conceiving clearly and fully the conditions of utility.
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
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
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
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
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
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
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
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.
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
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
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
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
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.
