Principles Holz I 47
Principle/Proof/Leibniz: from the principles of identity and experience (manifoldness is perceived by me) can be proved,
1. that a proof of it is impossible,
2. that all other sentences depend on it. (If they are not true, there is no knowledge at all).
I 47
Identity Principle/Leibniz: the identity principle is not derived from the senses, but is set with the senses.
Holz I 56
Reflexive principles/Leibniz:
1. the assumption that the syllogism is valid,
2. that the contradiction is paradoxical.
I 57
This is, however, formal and does not yet lead to a substantive positing of material truth.
Holz I 66
Truths of Reason/Leibniz: here there are two great principles:
1. the principle of non-contradiction
2. the principle of determining reason. (Sufficient reason).
I 67
"Although these determinant reasons are generally not sufficiently known, we still see that they are present." Insight into the existence of the reason is a priori, for the reason is nothing other than the inesse of the determining factor in the corresponding fact. (> Ratiocinatio: reduction to identical sentences).
