Between the truth which comes from God through His Prophets, and the glimmerings, often misunderstood and misinterpreted, of truth which come from the philosophers and thinkers, there is an immense difference. We must never, under any circumstances, confuse the two. Bahá'u'lláh has said that learning can be the veil between the soul of man and the eternal truth; in other words, between man and the knowledge of God. We have seen that many people who become very advanced in the study of modern physical sciences are led to deny God, and to deny His Prophets. That does not mean that God and the Prophets have not existed and do not exist. It only means that knowledge has become a veil between their hearts and the light of God.
