“The false interpreters of nature declare that quicksilver is the common seed of every metal, not remembering that nature varies the seed according to the variety of the things she desires to produce in the world.”

As quoted by Francis Preston Venable, A Short History of Chemistry (1894) p. 28. https://books.google.com/books?id=fN9YAAAAYAAJ&pg=PA28

Part III : Selection on Education from Kant's other Writings, Ch. I Pedagogical Fragments, # 13
The Educational Theory of Immanuel Kant (1904)
Context: There must be a seed of every good thing in the character of men, otherwise no one can bring it out. Lacking that, analogous motives, honor, etc., are substituted. Parents are in the habit of looking out for the inclinations, for the talents and dexterity, perhaps for the disposition of their children, and not at all for their heart or character.

Social Law in the Spiritual World (1904)
Context: The Inner Light is the doctrine that there is something Divine, "something of God," in the human soul.
Five words are used indiscriminately to name this Divine something: "The Light," "The Seed," "Christ within," "The Spirit," "That of God in you." This Divine Seed is in every person good or bad.

Leviathan (1651)
Context: The Interpretation of the Laws of Nature in a Common-wealth, dependeth not on the books of Moral Philosophy. The Authority of writers, without the Authority of the Commonwealth, maketh not their opinions Law, be they never so true.
