Dialectics is essentially the method or logos in which categories of forms are combined to explain things.Dialectics was developed because reason faces difficulties in grasping the sensible world.Practical wisdom is knowledge about some things or certain person or persons because of its variable objects.But it is not entirely specific or only about a particular thing and without universality in any sense.As one kind of dialectics,it combines various elements to accord with the right logos,similar to the way in which various forms are combined in theory.Therefore practical wisdom as a combination or polymerization of elements can be regarded as another kind of logic,namely practical logic or dialectics.
