§66.1Fr. 66
Th. de Affirmatione et negatione sic docuit, definitionem unam semper orationem eamque oportere continuatim proferri: illa enim una oratio esse dicitur, quae unius substantiae ̓εεὶξιω est.
Theophrastus in *On Affirmation and Negation* taught thus: that a definition is always a single speech, and that it must be uttered without interruption; for that is said to be a single speech which is the presentation of a single substance.
Definitio autem, ut v. gr. hominis, animal gressibile bipes, una est oratio per hoc, quoniam unum subjectum i. e. hominem ὁε.
But a definition, as for example of "human," "a two-footed walking animal," is a single speech by virtue of this: because it defines a single subject, that is, human.
Sin vero quis dividat et orationem unam rem significantem proferendi intermissione distribuat, multiplex fit oratio.
But if anyone should divide it and distribute a speech signifying a single thing by an interruption of uttering, the speech becomes multiple.
