“One resists the invasion of armies; one does not resist the invasion of ideas.”

“An invasion of armies can be resisted, but not an idea whose time has come”

“A beautiful woman is a casus belli; a pretty woman is flagrant misdemeanour. All the invasions of history have been determined by petticoats.”

“There is one thing stronger than all the armies in the world , and that is an idea whose time has come”

“No army can stop an idea whose time has come”

“No army can withstand the strength of an idea whose time has come.”

“There is a determined though unseen bravery that defends itself foot by foot in the darkness against the fatal invasions of necessity and dishonesty. Noble and mysterious triumphs that no eye sees, and no fame rewards, and no flourish of triumph salutes. Life, misfortunes, isolation, abandonment, poverty, are battlefields that have their heroes; obscure heroes, sometimes greater than the illustrious heroes.”
