When the subtle air, the impalpable, the sense that words and reason hold not, surround us and pervade us, Then I am charged with untold and untellable wisdom, I am silent, I require nothing further, I cannot answer the question of appearances or that of identity beyond the grave, But I walk or sit indifferent, I am satisfied, He ahold of my hand has completely satisfied me.
And now gentlemen, A word I give to remain in your memories and minds, As base and finalè too for all metaphysics.
(So to the students the old professor, At the close of his crowded course.)
