On military character, in 19 Stars : A Study in Military Character and Leadership (1981) by Edgar F. Puryear Jr.
Context: Dependability, integrity, the characteristic of never knowingly doing anything wrong, that you would never cheat anyone, that you would give everybody a fair deal. Character is a sort of an all-inclusive thing. If a man has character, everyone has confidence in him. Soldiers must have confidence in their leader.
“A Man must be very inert to have no character at all.”

If you’re in tune with your story then the characters do come at you organically. There isn’t an order to how they might appear.

Linear Associative Algebra (1882)
Context: All relations are either qualitative or quantitative. Qualitative relations can be considered by themselves without regard to quantity. The algebra of such enquiries may be called logical algebra, of which a fine example is given by Boole.
Quantitative relations may also be considered by themselves without regard to quality. They belong to arithmetic, and the corresponding algebra is the common or arithmetical algebra.
In all other algebras both relations must be combined, and the algebra must conform to the character of the relations.
