…it is our duty to put forth our greatest efforts and summon all our energies in order that the bonds of unity and accord may be established among mankind. For thousands of years we have had bloodshed and strife. It is enough; it is sufficient. Now is the time to associate together in love and harmony. For thousands of years we have tried the sword and warfare; let mankind for a time at least live in peace. Review history and consider how much savagery, how much bloodshed and battle the world has witnessed. It has been either religious warfare, political warfare or some other clash of human interests. The world of humanity has never enjoyed the blessing of universal peace. 
- ‘Abdu’l-Baha  (From a talk at Columbia University, New York, 19 April 1912; ‘The Promulgation of Universal Peace: Talks Delivered by 'Abdu'l-Bahá during His Visit to the United States and Canada in 1912’)
