Patrick Matthew,
On Naval Timber and Arboriculture
“ That Britain is leaving the impress of her energy and morality on a considerable portion of the world, is owing to her having first borne fire and sword over these countries: the husbandman tears up the glebe, with all its covering of weeds and flowers, before he commit his good seed to the earth. Life and death—good and evil—pleasure and pain, are the principles of impulse to the scheme or machine of nature, as heat and cold are to the steam-engine, thus moving in necessary alternate dependence. Our moral sense, our perception and love of good, could not exist without the knowledge of evil ”
