The Principle of Reason [75]

now tune in to how, in this sentence which speaks in a hollow unison, two different tonalities vibrate. We can say: "Nihil est sine ratione." "Nothing is without reason." In the affirmative form this means: everything has a reason.

Yet we can also set the pitch in this way: "Nihil est sine ratione." "Nothing is without reason." In the affirmative form this means: every being (as a being) has a reason. What does the principle of reason speak about?
