論通過自然選擇的物種起源，

或生存斗爭中優賦族群之保存

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.

——Whewell,Bridgewater Treatise

我們至少能夠說，我們得以看到，物質世界發生的事件，不是神力在每一特定場合的孤立干預所致，而是由于普遍法則的實施所致。

——惠威爾，《布里吉沃特論文集》

The only distinct meaning of the word‘natural'is stated,fixed or settled; since what is natural as much requires and presupposes an intelligent agent to render it so, i.e., to effect it continually or at stated times, as what is supernatural or miraculous does to effect it for once.

——Butler,Analogy of Revealed Religion

“自然的”一詞唯一獨特的意思是規定的、固定的或裁定的；正如所謂超自然的或神奇的事物需要或預先假定有一個智能的實體使其一蹴而成，所謂“自然的”事物則需要或預先假定有一個智能的實體不時地或在預定的時段進行干預，使之保持其特性。

——巴特勒，《啟示宗教之類比》

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

因而，任何人不應出于對莊重或節制的不當考慮，誤以為對上帝的話語或上帝的創作之書不應過分深入探究或過于仔細琢磨（無論是神學還是哲學方面）；相反，人們本應盡力地在這兩方面都追求無止境的進步或趨近嫻熟。
