His [Faraday's] third great discovery is the Magnetization of Light, which I should liken to the Weiss horn among mountains-high, beautiful, and alone.

In the firmament of science Mayer and Joule constitute a double star, the light of each being in a certain sense complementary to that of the other.

— John Tyndall

Knowledge once gained casts a light beyond its own immediate boundaries.

— John Tyndall

Taking him for all and all, I think it will be conceded that Michael Faraday was the greatest experimental philosopher the world has ever seen.

— John Tyndall

The logical feebleness of science is not sufficiently borne in mind. It keeps down the weed of superstition, not by logic but by slowly rendering the mental soil unfit for its cultivation.

— John Tyndall

... though he [Michael Faraday] took no cities, he captivated all hearts.

— John Tyndall

To him [Faraday], as to all true philosophers, the main value of a fact was its position and suggestiveness in the general sequence of scientific truth.

— John Tyndall

To Nature nothing can be added; from Nature nothing can be taken away; the sum of her energies is constant, and the utmost man can do in the pursuit of physical truth, or in the applications of physical knowledge, is to shift the constituents of the never-varying total. The law of conservation rigidly excludes both creation and annihilation. Waves may change to ripples, and ripples to waves; magnitude may be substituted for number, and number for magnitude; asteroids may aggregate to suns, suns may resolve themselves into flora and fauna, and floras and faunas melt in air: the flux of power is eternally the same. It rolls in music through the ages, and all terrestrial energy—the manifestations of life as well as the display of phenomena—are but the modulations of its rhythm.

— John Tyndall

Underneath his sweetness and gentleness was the heat of a volcano. [Michael Faraday] was a man of excitable and fiery nature; but through high self-discipline he had converted the fire into a central glow and motive power of life, instead of permitting it to waste itself in useless passion.
