5. Theory of Logic / B. Logical Consequence / 5. Modus Ponens

20309	If our ideas are adequate, what follows from them is also adequate [Spinoza]
	Full Idea: Whatever ideas follow in the mind from ideas which are adequate in the mind are also adequate.
	From: Baruch de Spinoza (The Ethics [1675], II Pr 40)
	A reaction: This appears to be Modus Ponens, and he calls it (in Sch 1) 'the foundations of our reasoning'. If 'adequate' ideas are knowledge, then this also seems to say that knowledge is closed under known implication.
