“The Pāṇinian commentator Kātyāyana (c. 3rd–4th century BCE) knew of the coexistence of Middle Indic forms with earlier ones. There is a Pāṇinian rule that provides that verb bases listed in an appendix to the Aṣṭādhyāyī have the class name dhātu (verbal base, root). Kātyāyana discusses whether one could define verbal bases semantically and thereby possibly do without the verb list. He remarks that even if one defines a verbal base as denoting an action, the roots must be listed in order to preclude the possibility that constituents of terms such as āṇapayati/āṇavayati ‘commands’ be assigned the class name in question; āṇapayati/āṇavayati is a Middle Indic counterpart of Sanskrit ājñāpayati.”

Precepts, Ch. 2, as translated by W. H. S. Jones (1923).
Context: Conclusions which are merely verbal cannot bear fruit, only those do which are based on demonstrated fact. For affirmation and talk are deceptive and treacherous. Wherefore one must hold fast to facts in generalizations also, and occupy oneself with facts persistently, if one is to acquire that ready and infallible habit which we call "the art of medicine."

“Criminal law therefore cannot be based on the notion of sin; it is crimes that it must define.”

Context: What is considered sinful in one of the great religions to which citizens belong isn't necessarily sinful in the others. Criminal law therefore cannot be based on the notion of sin; it is crimes that it must define.

Interviewed in the documentary series The Civil War, 1990
Context: Any understanding of this nation has to be based, and I mean really based, on an understanding of the Civil War. I believe that firmly. It defined us. The Revolution did what it did. Our involvement in European wars, beginning with the First World War, did what it did. But the Civil War defined us as what we are and it opened us to being what we became, good and bad things. And it is very necessary, if you are going to understand the American character in the twentieth century, to learn about this enormous catastrophe of the mid-nineteenth century. It was the crossroads of our being, and it was a hell of a crossroads.
