Full Idea
At this early period exegetical problems abound, since Leibniz uses 'force' both for actually acting forces and for potentials or powers.
Clarification
'exegesis' is interpretation
Gist of Idea
Leibniz uses 'force' to mean both activity and potential
Source
Gottfried Leibniz (works [1690], 9.II), quoted by Harré,R./Madden,E.H. - Causal Powers 9.II.B

A Reaction
I take Leibniz to be a key figure in the development of the Aristotelian approach, because he connected Aristotelian potential and essence with 'force' in the new physics. This is helpful in reading him correctly.
