G.W. Leibniz on Reason (Justification) - Dictionary of Arguments
Holz I 66
Proposition of sufficient reason/principle/Leibniz: "nothing happens without sufficient reason, without which it is possible for the person who is sufficiently acquainted with things to state a reason why it is so and not otherwise."
This is a derivative of the identity principle. Its validity is logically necessary.
Holz I 67
Reason/Leibniz: that something has a reason is that it does not exist from itself, not isolated per se.
Reason is the foundation of the world, in which every individual is admitted (> chain/Leibniz).
Holz I 75
Reason/Leibniz: can only be found by traversing the whole series rerum. It is, however, not to be found outside the series rerum, but completely within, but not at the beginning, but as the series as a whole!
Difference: while the infinite mind must stand outside the whole (as a depicting) (perhaps also an "unmoved mover", etc.), the reason (as a totality of the series) must be within the series.
Reason/Leibniz: the universal ultimate reason (totality of the series of things, world, ultima ratio) is also necessary for the finite mind because otherwise there would be nothing at all!_____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
