After watching the political conventions, this quote of Emerson's came to mind:

Amidst the downward tendency and proneness of things, when every voice is raised for a new road or another statute, or a subscription of stock, for an improvement in dress, or in dentistry, for a new house or a larger business, for a political party, or the division of an estate, — will you not tolerate one or two solitary voices in the land, speaking for thoughts and principles not marketable or perishable?
