National Book Award Acceptance Speech (1957)
Context: It is true that the poet does not directly address his neighbors; but he does address a great congress of persons who dwell at the back of his mind, a congress of all those who have taught him and whom he has admired; that constitute his ideal audience and his better self. To this congress the poet speaks not of peculiar and personal things, but of what in himself is most common, most anonymous, most fundamental, most true of all men. And he speaks not in private grunts and mutterings but in the public language of the dictionary, of literary tradition, and of the street. Writing poetry is talking to oneself; yet it is a mode of talking to oneself in which the self disappears; and the products something that, though it may not be for everybody, is about everybody.
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
