There's a meme floating around out there that is I think Grievous saying a condensed form of this quote from the Manifesto. If someone could point me to it I would be grateful, as I've been having trouble.

But don’t wrangle with us so long as you apply, to our intended abolition of bourgeois property, the standard of your bourgeois notions of freedom, culture, law, &c. Your very ideas are but the outgrowth of the conditions of your bourgeois production and bourgeois property, just as your jurisprudence is but the will of your class made into a law for all, a will whose essential character and direction are determined by the economical conditions of existence of your class.
