For as in the middest of the sea, though a man perceive no sound of that part of the water next to him; yet he is well assured that part contributes as much, to the Roaring of the Sea, as any other part, of the same quantity: so also, though wee perceive no great unquietnesse, in one, or two men; yet we may be well assured, that their singular Passions, are parts of the Seditious roaring of a trouble Nation.
