In optics, again, the Greeks found that the angle of incidence is equal to the angle of reflection; and their knowledge reached no further than to such simple deductions from this as their geometry sufficed for.
The author of the piece is entitled to much credit for the goodness of his pen, and I could wish he had as much credit for the rectitude of his heart; for, as men see through different optics, and are induced by the reflecting faculties of the mind to use different means to attain the same end, the author of the address should have had more charity than to mark for suspicion the man who should recommend moderation and longer forbearance; or, in other words, who should not think as he thinks, and act as he advises."
"You will become a proficient chemist, converting the substance of my remarks to airy nothings through your gospel-retorts." "Oh, I understand your optics as well. You like to see other folks; taking the bitters is another thing. The tea-bell is a tocsin." "Pshaw! You don't care to see any one! But shall there be no more cakes and ale? Haven't you any sympathy for a sweet tooth?" "None at all."
5 Colour as quality being no essential factor in the scientific explanation of the spectrum. 6 Contributions to Optics. 7 Outline of a Theory of Colour. 8 See Rudolf Steiner's edition of Goethe's Farbenlehre under Paralipomena zur Chromatik, No. 27. 9 Goethe's own representation of the phenomenon. 10 This is not to be confused with the meaning of 'purple' in modern English usage.
Oratory will not work against the stream, or on languid tides. Driblets of movements that allowed the world to doubt whether they were so much movements as illusions of the optics, did not suit his genius. Thus he was a Liberal, no Radical, fountain.
So that, to get materials for further advance, astronomy requires not only the indirect aid of the sciences which have presided over the making of its improved instruments, but the direct aid of an advanced optics, of barology, of thermology, of hygrometry; and if we remember that these delicate observations are in some cases registered electrically, and that they are further corrected for the "personal equation" the time elapsing between seeing and registering, which varies with different observers we may even add electricity and psychology.
As, therefore, these must be at best but speculative points of belief, which each individual, by reason of its obscurity, may contemplate with different optics, under various aspects, they surely ought to be left free for each to judge after his own fashion: the Hindoo can have no just cause of enmity against the Christian for his faith: this has no moral right to question the Mussulman upon his; the numerous sects of each of the various persuasions spread over the face of the earth, ought to make it a creed to look with an eye of complacency on the deviation of the others; and rest upon that great moral axiom, which is strictly conformable to Nature, which contains the whole of man's happiness "Do not unto another, that which do you not wish another should do unto you;" for it is evident, according to their own doctrines, out of all the variety of systems, one only can be right.
After such a watching as this, the very eye becomes disordered, as after looking at a bright color it sees a spectrum of a totally different tint; and, when the long looked-for person appears, he himself looks unnatural at first, and strange. How well many women know this curious fact in love's optics!
Five or six years ago I caused him to be taught in languages, mathematics, and optics, and I have gratuitously instructed him with my own lips since the time that I received your mandate. There is no one at Paris who knows so much of the root of philosophy, though he has not produced the branches, flowers, and fruit because of his youth, and because he has had no experience in teaching.
Mallard had got the vertigo, he reported the gambler's launch on dementedness to the earl. Gower's less experienced optics perceived it. The plainly doomed duellist with the insensible Black Goddess offered her all the advantages of the Immortals challenged by flesh.
