One of the chief peculiarities of this treatise is the doctrine that the true electric current, on which the electromagnetic phenomena depend, is not the same thing as the current of conduction, but that the time-variation of the electric displacement must [also] be taken into account.

James Clerk Maxwell

We define thermodynamics … as the investigation of the dynamical and thermal properties of bodies, deduced entirely from the first and second law of thermodynamics, without speculation as to the molecular constitution.
JAMES CLERK MAXWELL

Ampere was the Newton of Electricity.

I have been battering away at Saturn, returning to the charge every now and then. I have effected several breaches in the solid ring, and now I am splash into the fluid one, amid a clash of symbols truly astounding.
JAMES CLERK MAXWELL

It is a universal condition of the enjoyable that the mind must believe in the existence of a law, and yet have a mystery to move about in.
JAMES CLERK MAXWELL

Thus number may be said to rule the whole world of quantity, and the four rules of arithmetic may be regarded as the complete equipment of the mathematician.

The mind of man has perplexed itself with many hard questions. Is space infinite, and in what sense? Is the material world infinite in extent, and are all places within that extent equally full of matter? Do atoms exist or is matter infinitely divisible?
JAMES CLERK MAXWELL

Extent Hard Infinite Itself Man Many Material Mind Place Prep; Exed Question Space World
But I think that the results which each man arrives at in his attempts to harmonize his science with his Christianity ought not to be regarded as having any significance except to the man himself, and to him only for a time, and should not receive the stamp of a society.
JAMES CLERK MAXWELL

In the heavens we discover [stars] by their light, and by their light alone … the sole evidence of the existence of these distant worlds … that each of them is built up of molecules of the same kinds we find on earth.
JAMES CLERK MAXWELL

Alone Built Discover Distant Each Evidence Existence Heaven Light Sole Star Word
I think it ought to occupy a prominent place in our investigations, and that we ought to endeavour to construct a mental representation of all the details of its action, and this has been my constant aim in this treatise.

The true Logic for this world is the Calculus of Probabilities, which takes account of the magnitude of the probability.

But that we may find illustrations of the highest doctrines of science in games and gymnastics, in travelling by land and by water, in storms of the air and of the sea, and wherever there is matter in motion.

We can scarcely avoid the inference that light consists in the transverse undulations of the same medium which is the cause of electric and magnetic phenomena.
JAMES CLERK MAXWELL

The experimental investigation by which Ampere established the law of the mechanical action between electric currents is one of the most brilliant achievements in science. The whole, theory and experiment, seems as if it had leaped, full grown and full armed, from the brain of the ‘Newton of Electricity’.

The only laws of matter are those that our minds must fabricate and the only laws of mind are fabricated for it by matter.

Heat may be generated and destroyed by certain processes, and this shows that heat is not a substance.
JAMES CLERK MAXWELL

The equations at which we arrive must be such that a person of any nation, by substituting the numerical values of the quantities as measured by his own national units, would obtain a true result.
