To oppose knowledge is ignorant, and he who detests knowledge and science is not a man, but rather an animal without intelligence. For knowledge is light, life, felicity, perfection, beauty and the means of approaching the Threshold of Unity. It is the honor and glory of the world of humanity, and the greatest bounty of God. Knowledge is identical with guidance, and ignorance is real error
Abdu'l-BaháIf religious beliefs and opinions are found contrary to the standards of science they are mere superstitions and imaginations.
Abdu'l-BaháTo attain eternal happiness one must suffer. He who has reached the state of self-sacrifice has true joy. Temporal joy will vanish.
Abdu'l-BaháThe confirmations of the Spirit are all those powers and gifts which some are born with (and which men sometimes call genius), but for which others have to strive with infinite pains. They come to that man or woman who accepts his life with radiant acquiescence.
Abdu'l-BaháReligion should unite all hearts and cause wars and disputes to vanish from the face of the earth; it should give birth to spirituality, and bring light and life to every soul. If religion becomes a cause of dislike, hatred and division, it would be better to be without it... Any religion which is not a cause of love and unity is no religion.
Abdu'l-Bahá
