Note 59 — Chapter V · LOGIC OF THE STOICS.
Oswald J. (Oswald Joseph) Reichel translation
(2) Incomplete expression. (a) The grammar of words. In the section devoted to incomplete expression, much is found which we should include under grammar rather than under logic. Thus all incomplete expressions are divided into two groups—one group includes proper names and adjectives, the other includes verbs.59 These two groups are used respectively to express what is essential and what is accidental,60 and are again divided into a number of subdivisions and varieties.61 To this part of logic investigations into the formation and division of conceptions, and the doctrine of the categories, properly belong; but it cannot be said with certainty what place they occupy in the logic of the Stoics.62
