I think the effective use of quotation is an important point in the art of writing. Given sparingly, quotations serve admirably as a climax or as a corroboration, but when they are long and frequent, they seriously weaken the effect of a book. We lose sight of the writer - he scatters our sympathy among others than himself - and the ideas which he himself advances are not knit together with our impression of his personality.
George EliotIf you deliver an opinion at all, it is mere stupidity not to do it with an air of conviction and well-founded knowledge. You make it your own in uttering it, and naturally get fond of it.
