Science arises from the discovery of Identity amid Diversity.
William Stanley Jevons
Image
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
Image
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
Image
The calculus of utility aims at supplying the ordinary wants of man at the least cost of labour.
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
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
The difficulties of economics are mainly the difficulties of conceiving clearly and fully the conditions of utility.
William Stanley Jevons
Image
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
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
Image
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
Image
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
Image
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
Image
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
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
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
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.

Image
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
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
A correct theory is the first step towards improvement, by showing what we need and what we might accomplish.

The child which overbalances itself in learning to walk is experimenting on the law of gravity.
