The genius of the Spanish people is exquisitely subtle, without being at all acute; hence there is so much humour and so little wit in their literature.
It is saying less than the truth to affirm that an excellent book (and the remark holds almost equally good of a Raphael as of a Milton) is like a well-chosen and well-tended fruit tree. Its fruits are not of one season only. With the due and natural intervals, we may recur to it year after year, and it will supply the same nourishment and the same gratification, if only we ourselves return to it with the same healthful appetite.
...from the time of Kepler to that of Newton, and from Newton to Hartley, not only all things in external nature, but the subtlest mysteries of life and organization, and even of the intellect and moral being, were conjured within the magic circle of mathematical formulae.
In wonder all philosophy began, in wonder it ends, and admiration fill up the interspace; but the first wonder is the offspring of ignorance, the last is the parent of adoration.
We ought not to extract pernicious honey from poison blossoms of misrepresentation and mendacious half-truth, to pamper the course appetite of bigotry and self-love.
Some persons have contended that mathematics ought to be taught by making the illustrations obvious to the senses. Nothing can be more absurd or injurious: it ought to be our never-ceasing effort to make people think, not feel.
A State, in idea, is the opposite of a Church. A State regards classes, and not individuals; and it estimates classes, not by internal merit, but external accidents, as property, birth, etc. But a church does the reverse of this, and disregards all external accidents, and looks at men as individual persons, allowing no gradations of ranks, but such as greater or less wisdom, learning, and holiness ought to confer. A Church is, therefore, in idea, the only pure democracy.
Centres, or centre-pieces of wood, are put by builders under an arch of stone while it is in the process of construction till the keystone is put in. Just such is the use Satan makes of pleasures to construct evil habits upon; the pleasure lasts till the habit is fully formed; but that done the habit may stand eternal. The pleasures are sent for firewood, and the hell begins in this life.
What! Did Sir W[alter] R[aleigh] believe that a male and female ounce (and, if so, why not two tigers and lions, etc?) would have produced, in a course of generations, a cat, or a cat a lion? This is Darwinizing with a vengeance.
To all new truths, or renovation of old truths, it must be as in the ark between the destroyed and the about-to-be renovated world. The raven must be sent out before the dove, and ominous controversy must precede peace and the olive wreath.
