Brainerd Kellogg, 1892

Thoughts and words borrowed from great writers and speakers—may fitly be used anywhere and by any one. One’s discourse should not be a patchwork to which others have contributed as much as he has, but the occasional and happy use of quotations betrays an acquaintance with authors that is grateful to reader or hearer. Arraying behind his thought names greater than his own, these quotations give to what he says authority which without such re-enforcement it could not have.
