I cannot stand forward, and give praise or blame to any thing which relates to human actions, and human concerns, on a simple view of the subject as it stands stripped of every relation, in all the nakedness and solitude of metaphysical abstraction. Circumstances (which with some gentlemen pass for nothing) give in reality to every political principle its distinguishing colour, and discriminating effect. The circumstances are what render every civil and political scheme beneficial or noxious to mankind.

— Edmund Burke
