Margaret Thatcher photo

“You may have to fight a battle more than once to win it.”

Margaret Thatcher (1925–2013) British stateswoman and politician

This quote is widely attributed to Margaret Thatcher on various websites, and also appears in a number of books, including The Concise Columbia Dictionary of Quotations, Columbia University Press (1989), ed. Robert Andrews, p. 320 : ISBN 0231069901. 9780231069908 , but without any further source information such as date, location or any other context.
One valid Thatcher quote which may be the basis for the version above appears in the Second Carlton Lecture http://www.margaretthatcher.org/document/105799 (‘Why Democracy Will Last’), delivered at the Carlton Club, London (November 26, 1984) : Mr. Chairman, each generation has to stand up for democracy. It can’t take anything for granted and may have to fight fundamental battles anew. You know that marvellous quotation from Goethe : ‘That which thy fathers bequeathed thee / Earn it anew if thou would possess it.’
Thatcher also expressed this thought in a Speech to Atlantic Bridge (May 14, 2003) http://www.margaretthatcher.org/document/111266, delivered at the St. Regis Hotel, New York City : My friends, every generation has to fight anew the battle for liberty.

Mahatma Gandhi photo

“Live as if you were to die tomorrow. Learn as if you were to live forever.”

Mahatma Gandhi (1869–1948) pre-eminent leader of Indian nationalism during British-ruled India

Variant on aphorism "Study as if you were to live forever. Live as if you were to die tomorrow" pre-dating Gandhi, variously attributed to Isidore of Seville (c. 560 – 636), in FPA Book of Quotations (1952) by Franklin Pierce Adams, to Edmund Rich (1175–1240) in American Journal of Education (1877), or to Alain de Lille in Samuel Smiles's Duty https://books.google.com/books?id=33UzAAAAMAAJ&pg=PA363&dq=live+die+tomorrow+learn+forever&hl=en&sa=X&ved=0ahUKEwjd3s_2m57MAhWFMGMKHe-sAl8Q6AEIHDAA#v=onepage&q=live%20die%20tomorrow%20learn%20forever&f=false (1881).
The 1995 book "The good boatman: a portrait of Gandhi," states that Gandhi subscribed "to the view that a man should live thinking he might die tomorrow but learn as if he would live forever."
In his 2010 Boyer lecture Glyn Davis (Professor of Political Science and Vice-Chancellor of Melbourne University) attributes the quote to Desiderius Erasmus. "He [Erasmus] reworked Pliny to urge 'live as if you are to die tomorrow, study as if you were to live forever'. Many students obey the first clause - the best heed both."
There is a similar quote by Johann Gottfried Herder: "Mensch, genieße dein Leben, als müssest morgen du weggehn; Schone dein Leben, als ob ewig du weiletest hier." ["Man, enjoy your life as if you were to depart tomorrow; spare your life as if you were to linger here forever."] (Zerstreute Blätter, 1785).

“Fairy tales are more than true: not because they tell us that dragons exist, but because they tell us that dragons can be beaten.”

Often misattributed to but inspired by GK Chesterton:
Fairy tales do not give the child his first idea of bogey. What fairy tales give the child is his first clear idea of the possible defeat of bogey. The baby has known the dragon intimately ever since he had an imagination. What the fairy tale provides for him is a St. George to kill the dragon.

According to The Quote Investigator http://quoteinvestigator.com/2014/04/17/butterfly/, "the earliest instance of this saying was crafted by the enigmatic “L” for “The Daily Crescent” newspaper in New Orleans [in June 1848]. ... The linkage to Henry David Thoreau is unsupported."

""Our civilization is a perilous adventure for an uncertain prize... Human society is not a constructed thing but a human organization... We are adopting a false method of reform when we begin by operations that weaken society, either morally or materially, by lower its vitality, by plunging it into gloom and despair about itself, by inducing the atmosphere of the sick-room, and then when its courage and resources are at a low ebb, expecting it to perform some mighty feat of self-reformation... Social despair or bitterness does not get us anywhere... Low spirits are an intellectual luxury. An optimist is one who sees an opportunity in every difficulty. A pessimist is one who sees a difficulty in every opportunity... The conquest of great difficulties is the glory of human nature." L. P. Jacks, quoted in American character, by Brander Matthews, 1906
