John Tyndall Quotes

Life is a wave, which in no two consecutive moments of its existence is composed of the same particles.

Then arose the sect of the Gnostics—men who know — who laid claim to the possession of a perfect science, and who, if they were to be believed, had discovered the true formula for what philosophers called 'the Absolute.' But these speculative Gnostics were rejected by the conservative and orthodox Christians of their day as fiercely as their successors the Agnostics —men who don't know—are rejected by the orthodox in our own.

The mind of man may be compared to a musical instrument with a certain range of notes, beyond which in both directions we have an infinitude of silence.

I leave it to you to compare this Christian hero <nowiki>[</nowiki>Paul] with some of the 'freethinkers' of our own day, who, 'more intolerant than the intolerance they deprecate,' flaunt in public their cheap and trumpery theories of the great Apostle and the Master whom he served.

Those who are unacquainted with the details of scientific investigation have no idea of the amount of labour expended in the determination of those numbers on which important calculations or inferences depend. They have no idea of the patience shown by a Berzelius in determining atomic weights; by a Regnault in determining coefficients of expansion; or by a Joule in determining the mechanical equivalent of heat.

That there were 'weeds' in the Bible requiring to be kept out of sight was to me... a new revelation. I take little pleasure in dwelling upon the errors and blemishes of a book rendered venerable to me by intrinsic wisdom and imperishable associations. But...when its passages are invoked to justify the imposition of a yoke, irksome because unnatural, we are driven in self-defence to be critical.

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 florae and faunae, 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.

When arguments or proofs were needed, whether on the side of the Jewish Christians or of the Gentile Christians, a document was discovered which met the case, and on which the name of an apostle, or of some authoritative contemporary of the apostles, was boldly inscribed. The end being held to sanctify the means, there was no lack of manufactured testimony.

Discussion, therefore, is one of the motive powers of life, and, as such, is not to be deprecated.

[W]aste in intellect may be as much an incident of growth as waste in nature.

Christian love was not the feeling which long animated the respective followers of Peter and Paul.
We who have been born into a settled state of things can hardly realise the commotion out of which this tranquillity has emerged. We have, for example, the canon of Scripture already arranged for us. But to sift and select these writings from the mass of spurious documents afloat at the time of compilation was a work of vast labour, difficulty, and responsibility. The age was rife with forgeries. Even good men lent themselves to these pious frauds, believing that true Christian doctrine, which of course was their doctrine, would be thereby quickened and promoted. There were gospels and counter-gospels; epistles and counter-epistles—some frivolous, some dull, some speculative and romantic, and some so rich and penetrating, so saturated with the Master's spirit, that, though not included in the canon, they enjoyed an authority almost equal to that of the canonical books.

A point highly illustrative of the character of Faraday now comes into view. He gave an account of his discovery of Magneto-electricity in a letter to his friend M. Hachette, of Paris, who communicated the letter to the Academy of Sciences. The letter was translated and published ; and immediately afterwards two distinguished Italian philosophers took up the subject, made numerous experiments, and published their results before the complete memoirs of Faraday had met the public eye. This evidently irritated him. He reprinted the paper of the learned Italians in the Philosophical Magazine accompanied by sharp critical notes from himself. He also wrote a letter dated Dec. 1,1832, to Gay Lussac, who was then one of the editors of the Annales de Chimie in which he analysed the results of the Italian philosophers, pointing out their errors, and' defending himself from what he regarded as imputations on his character. The style of this letter is unexceptionable, for Faraday could not write otherwise than as a gentleman; but the letter shows that had he willed it he could have hit hard. We have heard much of Faraday's gentleness and sweetness and tenderness. It is all true, but it is very incomplete. You cannot resolve a powerful nature into these elements, and Faraday's character would have been less admirable than it was had it not embraced forces and tendencies to which the silky adjectives "gentle" and "tender" would by no means apply. Underneath his sweetness and gentleness was the heat of a volcano. He 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. "He that is slow to anger" saith the sage, "is greater than the mighty, and he that ruleth his own spirit than he that taketh a city." Faraday was not slow to anger, but he completely ruled his own spirit, and thus, though he took no cities, he captivated all hearts.

Superstition may be defined as constructive religion which has grown incongruous with intelligence.

The Sabbath being regarded as a shadow or type of that heavenly repose which the righteous will enjoy when this world has passed away, 'so these six days of creation are so many periods or millenniums for which the world and the toils and labours of our present state are destined to endure.' The Mosaic account was thus reduced to a poetic myth... But if this symbolic interpretation, which is now generally accepted, be the true one, what becomes of the Sabbath day? It is absolutely without ecclesiastical meaning. The man who was executed for gathering sticks on that day must therefore be regarded as the victim of a rude legal rendering of a religious epic.

With terrible jolts and oscillations the religious life of the world has run down 'the ringing grooves of change.' A smoother route may have been undiscoverable. At all events it was undiscovered.
