On the Origin of Species by Means of Natural Selection,
or the
Preservation of Favoured Races in the Struggle for Life.

By Charles Darwin

Preface.
"But with regard to the material world, we can at least go so far as this -- we can perceive that events are brought about not by insulated interpositions of Divine power, exerted in each particular case, but by the establishment of general laws."

W. Whewell: Bridgewater Treatise.
"To conclude, therefore, let no man out of a weak conceit of sobriety, or an ill-applied moderation, think or maintain, that a man can search too far or be too well studied in the book of God's word, or in the book of God's works; divinity or philosophy; but rather let men endeavour an endless progress or proficience in both."

Bacon: Advancement of Learning.
Down, Bromley, Kent,
October 1st, 1859.
