Courtesy is among the hallmarks of the human reality, an attribute whereby man is distinguished above all else. Whoso hath not attained thereunto, his non-existence is assuredly preferable to his existence.
- Baha’u’llah (‘Additional Tablets and Extracts from Tablets Revealed by Bahá’u’lláh’; Baha’i Reference Library of the Baha’i World Center)
