Why is man so hard of heart? It is because he does not yet
know God. If he had knowledge of God he could not act in direct opposition to
His laws; if he were spiritually minded such a line of conduct would be
impossible to him. If only the laws and precepts of the prophets of God had
been believed, understood and followed, wars would no longer darken the face of
the earth.

'Abdu'l-Bahá in Paris in 1911-1912’)
