- O Plato! O Pythagoras! ages ago you heard these harmonies, surprised these moments of inward ecstasy, — knew these divine transports! If music thus carries us to heaven, it is because music is harmony, harmony is perfection, perfection is our dream, and our dream is heaven.
- Henri-Frédéric Amiel, Journal Intime (1882), entry for 17 March 1870.
- I'd like to teach the world to sing
In perfect harmony
I'd like to hold it in my arms and keep it company.
I'd like to see the world for once
All standing hand in hand
And hear them echo through the hills "Ah, peace throughout the land."
That's the song I hear...
- Billy Davis (working with Bill Backer, Roger Cook, and Roger Greenway) in "I'd Like to Teach the World to Sing" - Video of The New Seekers rendition at YouTube (with lyrics).
- Virtue is harmony, and health, and universal good, and God; on which account everything owes its existence and consistency to harmony.
- Relativity does set limits on what humans can ultimately do. But the universe is not required to be in perfect harmony with human aspirations.
- There is a spirit in man and in the world working always against the thing that destroys and lays waste. Always he must know that the contradictions of life are not final or ultimate; he must distinguish between failure and a many-sided awareness so that he will not mistake conformity for harmony, uniformity for synthesis. He will know that for all men to be alike is the death of life in man, and yet perceive harmony that transcends all diversities and in which diversity finds its richness and significance.
- Howard Thurman, The Search For Common Ground : An Inquiry Into The Basis Of Man's Experience Of Community (1971), p. 6.
- Each and every master, regardless of the era or the place, heard the call and attained harmony with heaven and earth. There are many paths leading to the top of Mount Fuji, but there is only one summit — love.
- Morihei Ueshiba, as quoted in You Can Save the Earth: 7 Reasons Why and 7 Simple Ways, a Philosophy for the Future (2008) by Hatherleigh, Sean K. Smith, and Andrew Flach, p. 92.
- My temper leads me to peace and harmony with all men; and it is peculiarly my wish to avoid any personal feuds or dissensions with those, who are embarked in the same great national interest with myself, as every difference of this kind in its consequence must be very injurious.
- George Washington, in a letter to Major-General Gates (24 February 1778); published in The Writings of George Washington (1890) edited by Worthington Chauncey Ford, p. 368.
- Observe good faith and justice towards all Nations; cultivate peace and harmony with all. Religion and Morality enjoin this conduct; and can it be, that good policy does not equally enjoin it?
