In the Second Part of the Ethics, on the contrary, the same commentators manifest difficulty in recognizing limitless fidelity to the method. However, it is an apparent difficulty. This paper focuses the initial definitions of the Second Part of the Ethics, having for goal to seat out that they are related among themselves according to a precise formal arrangement.
