“The moment one constructs a device to carry into practice a crude idea, he finds himself unavoidably engrossed with the details of the apparatus. As he goes on improving and reconstructing, his force of concentration diminishes and he loses sight of the great underlying principle.… I do not rush into actual work. When I get an idea, I start at once building it up in my imagination. I change the construction, make improvements and operate the device in my mind. It is absolutely immaterial to me whether I run my turbine in thought or test it in my shop. I even note if it is out of balance.”

A Treatise on Isoperimetrical Problems, and the Calculus of Variations (1810)
Context: There is another point... and that is the method of demonstration by geometrical figures. In the first solution of Isoperimetrical problems, the Bernoullis use diagrams and their properties. Euler, in his early essays, does the same; then, as he improves the calculus he gets rid of constructions. In his Treatise [footnote: Methodus inveniendi, &c. ], he introduces geometrical figures, but almost entirely, for the purpose of illustration: and finally, in the tenth volume of the Novi Comm. Petrop. as Lagrange had done in the Miscellanea Taurinensea, he expounds the calculus, in its most refined state, entirely without the aid of diagrams and their properties. A similar history will belong to every other method of calculation, that has been advanced to any degree of perfection. <!--Preface p. vii-viii

Context: Orgoch gave a most ungentle snort. Orddu, meanwhile, had unfolded a length of brightly woven tapestry and held it out to Taran.
“We came to bring you this, my duckling,” she said. “Take it and pay no heed to Orgoch’s grumbling. She’ll have to swallow her disappointment—for lack of anything better.”
“I have seen this on your loom,” Taran said, more than a little distrustful. “Why do you offer it to me? I do not ask for it, nor can I pay for it.”
“It is yours by right, my robin,” answered Orddu. “It does come from our loom, if you insist on strictest detail, but it was really you who wove it.”
Puzzled, Taran looked more closely at the fabric and saw it crowded with images of men and women, of warriors and battles, of birds and animals. “These,” he murmured in wonder, “these are of my own life.”
“Of course,” Orddu replied. “The pattern is of your choosing and always was.”
“My choosing?” Taran questioned. “Not yours? Yet I believed...” He stopped and raised his eyes to Orddu. “Yes,” he said slowly, “once I did believe the world went at your bidding. I see now it is not so. The strands of life are not woven by three hags or even by three beautiful damsels. The pattern indeed was mine. But here,” he added, frowning as he scanned the final portion of the fabric where the weaving broke off and the threads fell unraveled, “here it is unfinished.”
“Naturally,” said Orddu. “You must still choose the pattern, and so must each of you poor, perplexed fledglings, as long as thread remains to be woven.”
