Some quotations are funny, or pithy, together with longer ones that record the words of a scientist about their own discoveries or outlook.
Maturin M. Ballou, in the Preface to his Edge-Tools of Speech (1899), wrote: “To be of greatest value quotations must be accurately given; but the readiest memory seldom retains more than the aggregated sense of an aphoristic utterance.” Therefore, some familiar quotes cannot be traced to a verbatim source. Nevertheless, “According to Dean Swift, abstracts, abridgments, summaries, etc., have the same use as burning-glasses, — to collect the diffused rays of wit and learning, and make them point with warmth and quickness upon the reader's imagination.”
