“Everyone is entitled to his own opinion, but not his own facts.”
Quoted in Robert Sobel's review of Past Imperfect: History According to the Movies edited by Mark C. Carnes.
Quoted in Timothy J. Penny, http://www.nationalreview.com/article/207925/facts-are-facts-timothy-j-penny, National Review September 4, 2003.
Ellen Hume, Tabloids, Talk Radio and the Future of News, part 4 http://www.ellenhume.com/articles/tabloids4.html ( TOC http://www.ellenhume.com/articles/tabloids_contents.html), 1995 cites this as something Moynihan said to a "1994 electoral opponent on WNBC in New York".
However, proceedings http://web.archive.org/web/20141031220947/http://www.intelligence.senate.gov/pdfs/96id_protection.pdf of a Senate Intelligence Committee in 1980 attribute the identical quote to James R. Schlesinger (at p. 110), possibly made during the course of 1973 Congressional testimony.
Also see Bernard Baruch, who said "Every man has a right to his own opinion, but no man has a right to be wrong in his facts." in the January 6, 1950 issue of the Deming (New Mexico) Headlight

“Everyone is in love with his own ideas”

“Everyone is master of his own destiny.”
Remark (23 June 1972), as quoted in Transitions to a Heart Centered World : Through the Kundalini Yoga and Meditations of Yogi Bhajan (1988) by Guru Rattana and Ann M. Maxwell, p. 107
Context: Everyone is master of his own destiny. Those who do not know how to be commanded do not know how to command. Temptation is the law of Maya (illusion). One who can withstand it knows the law of life: assess your 1) stamina 2) potential 3) basic flexibility, and know where your emotions are.
