Portrait of Goold Brown Goold Brown,  The Grammar of English Grammars (1882)

“ The Indicative mood is that form of the verb, which simply indicates or declares a thing: as, I write; you know: or asks a question; as, "Do you know?"--"Know ye not?"
The Potential mood is that form of the verb which expres ses the power, liberty, possibility, or necessity, of the being, action, or passion: as, "I can walk; he may ride; we must go."
The Subjunctive mood is that form of the verb, which represents the being, action, or passion, as conditional, doubtful, and contingent: as, "If thou go, see that thou offend not."--"See thou do it not."--Rev., xix, 10.

“ In short, the idea of a "subjunctive mood in the indicative form," (which is adopted by Chandler, Frazee, Fisk, S. S. Greene, Comly, Ingersoll, R. C. Smith, Sanborn, Mack, Butler, Hart, Weld, Pinneo, and others,) is utterly inconsistent with any just notion of what a mood is; and the suggestion, which we frequently meet with, that the regular indicative or potential mood may be thrown into the subjunctive by merely prefixing a conjunction, is something worse than nonsense. Indeed, no mood can ever be made a part of an other, without the grossest confusion and absurdity. ”
