In a note to quot. 1817, Coleridge says: ‘I am aware that this word occurs neither in Johnson's Dictionary nor in any classical writer. But the word, ‘to intend’, which Newton and others before him employ in this sense, is now so completely appropriated to another meaning, that I could not use it without ambiguity: while to paraphrase the sense, as by render intense, would often break up the sentence and destroy that harmony of the position of the words with the logical position of the thoughts, which is a beauty in all composition, and more especially desirable in a close philosophical investigation. I have therefore hazarded the word, intensify; though, I confess, it sounds uncouth to my own ear’.]
