2. Analytical Introduction (6)

2.1.3. logica docens (logic for teaching) and logica utens (logic for use)

a) Preliminary notions

1. logica docens is logic as proposing in a demonstrative way the necessary rules to arrive at knowledge (scientia) in a perfect state.
2. logica utens is logic as applying these rules to a particular case.

b) Thesis

1. statement: logica utens is the same habitude as logica docens.
2. demonstration:
i) from the specific object of both
logica docens and logica utens both have for their specific object the order of conspets, and they differ only insofar as logica utens considers such order under the practical aspect of application to research.
ii) from the notion of habitus
M A new habitus is necessary where there is a new difficulty to conquer, a new indetermination to remove;
m but such a new difficulty is not found in applying knowledge of logic: in fact this follows necessarily, on account of abstraction from whence come the concepts;
C The application of knowledge of logic does not require a new habitus.
3. Nota Bene: There is a difference between logical scientia and moral scientia. In the latter, a new habitus is necessary, viz. prudence, since one passes from the human act considered in abstracto, universally and necessarily, to the concrete act, individual and contingent. Since there is a special difficulty in the application of moral science, the virtue of prudence intervenes.
