inter-determination and opposition
inter-determination : the positing of an activity in one thing immediately leads to the positing of a passivity in its opposite, and vice versa.
the principle of opposition : if ,in general, a passivity is to be posited, it must be posited in the opposite of what is active.
A passivity is posited in the self, that is, a quantum of its activity is abolished.
... the absolute existence of the self cannot be given up . . .
that our idealism is not dogmatic but practical; does not determine what IS, but what OUGHT TO BE )
