“Books appear to be the most immediate instruments of speculative delight.”

“Considering that Timur had ignored every instrument of government except terror, it is remarkable his immediate successors managed to retain control of most of his empire.”

“Of all man’s instruments, the most wondrous, no doubt, is the book. The other instruments are extensions of his body. The microscope, the telescope, are extensions of his sight; the telephone is the extension of his voice; then we have the plow and the sword, extensions of the arm. But the book is something else altogether: the book is an extension of memory and imagination.”

“A book unwritten is a delightful universe of infinite possibilities. Set down one word, however, and it immediately becomes earthbound. Set down one sentence and it’s halfway to being just like every other bloody book that’s ever been written.”

“Love is the most melodious of all harmonies and the sentiment of love is innate. Woman is a delightful instrument of pleasure, but it is necessary to know its trembling strings, to study the position of them, the timid keyboard, the fingering so changeful and capricious which befits it.”

“Most areas of intellectual life have discovered the virtues of speculation, and have embraced them wildly. In academia, speculation is usually dignified as theory.”
