Knowledge of Causes

"It is a correct position that True Knowledge is Knowledge by Causes."—Novum Organum ii.2.

" All Knowledge doth much depend upon the Knowledge of Causes."— Advice to Rutland (Letters and Life , James Spedding ii. 14)


Pol : I have found

The very cause of Hamlet's lunacy....
I will be brief. Your noble son is mad....
Mad let us grant him then; and now remains
That we find out the cause of this effect,
Or rather say, the causes of this defect,
For this effect defective comes by cause."
Hamlet ii.2

The latter words are almost repeated in Bohn's translation of the Second Book of the Novum Organum, but in Spedding's Edition of the Works the conjunction and repetition of the words cause, effect, and defect is avoided, and the resemblance obscured by the use of more high-sounding words—efficient, material, discovery, operation)

Lear : "First let me talk with this philosopher.
What is the cause of thunder?"
Lear iii. 4 - Sir Francis Bacon's New Advancement of Learning
