After delivering the message of God and
explaining the divine teachings, the Master spoke humorously about the
philosophers:
They say that had there been a
spiritual world they would have sensed it. But, as a matter of fact, inability
to sense a thing is not a proof of the nonexistence of that thing. If inability
to sense constitutes proof of perfection, the cow must be the greatest
philosopher, for she does not realize anything beyond the animal world. (‘Abdu’l-Baha,
from a conversation, August 5, 1912, Dublin, USA; ‘Mahmud’s Diary’)
