Thomas Paine 

These are the times that try men's souls.  The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of his country;  but he that stands it now deserves the love and thanks of man and woman.  Tyranny, like hell, is not easily conquered;  yet we have this consolation with us -- that the harder the conflict, the more glorious the triumph.

 

         -Thomas Paine (The American Crisis 1770-1783)

Immediate necessity makes many things convenient which, if continued, would grow into oppressions.

When we are planning for posterity, we ought to remember that virtue is not hereditary.

         -Thomas Paine (Common Sense  1776)

Thomas Paine.  1737-1809.  American political theorist and writer.  Born England;  came to America 1774.  His Common Sense (Jan, 1776) hastened Declaration of Independence, and his pamphlet series The American Crisis heartened patriots in the Revolution.
