Nature always works tardily, and, as it were, thriftily; her operations are never violent; even in her productions she requires temperance; she never works but by rule and measure; if she be hurried she soon falls into decline, and employs all her remaining strength in self-preservation, losing entirely her productive faculty and productive power.

Context

“I look upon a good Mussulman as an athlete, destined to strive without respite, but who, soon weakened and overcome by his first toils, languishes even in the field of victory, and finds himself, so to speak, buried under his own triumphs. Nature always works tardily, and, as it were, thriftily; her operations are never violent; even in her productions she requires temperance; she never works but by rule and measure; if she be hurried she soon falls into decline, and employs all her remaining strength in self-preservation, losing entirely her productive faculty and productive power. It is to this state of debility that we are always reduced by the great number of our wives, fitter to exhaust us than to satisfy us. It is quite common among us to see a man in a very large seraglio with but few children.” source
