The limitation of the philosophical doctrines to be considered, to the system of Kant, is not exclusive.This is to be distinguished from having the object brought under my disposal (in potestatem meam reductum), which supposes not a capability merely, but also a particular act of the free-will.And this title constitutes the right to impose upon all others an obligation, not otherwise laid upon them, to abstain from the use of certain objects of our free choice, because we have already taken them into our possession.
