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".

From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.
