It is a fair summary of history to say that the safeguards of liberty have been forged in controversies involving not very nice people.
Interpretation
Liberty is often defended by engaging with controversial figures and ideas.
Felix Frankfurter's quote highlights the complex nature of liberty and its preservation throughout history. It suggests that the foundations of freedom have often emerged from contentious debates and the actions of individuals who may not conform to conventional standards of morality, implying that the struggle for liberty requires grappling with uncomfortable truths and challenging personalities.
In practice
During a speech on civil rights, one might use this quote to emphasize the importance of engaging with all facets of historical debate.
Ultimately there can be no freedom for self unless it is vouchsafed for others; there can be no security where there is fear, and a democratic society presupposes confidence and candor in the relations of men with one another and eager collaboration for the larger ends of life instead of the pursuit of petty, selfish or vainglorious aims.
The accretion of dangerous power does not come in a day. It does come, however slowly, from the generative force of unchecked disregard of the restrictions that fence in even the most disinterested assertion of authority.
Democracy is always a beckoning goal, not a safe harbor. For freedom is an unremitting endeavor, never a final achievement.
Without a free press there can be no free society. That is axiomatic. However, freedom of the press is not an end in itself but a means to the end of a free society. The scope and nature of the constitutional guarantee of the freedom of the press are to be viewed and applied in that light.
The words of the Constitution... are so unrestricted by their intrinsic meaning or by their history or by tradition or by prior decisions that they leave the individual Justice free, if indeed they do not compel him, to gather meaning not from reading the Constitution but from reading life.
Litigation is the pursuit of practical ends, not a game of chess.
The history of the world - by which, of course, we mean Europe - is a record of intertribal lacerations, of ethnic cleansings.
The Edmund Pettus Bridge - which in 2013 was declared a National Historic Landmark - isn't symbolic of the Civil War in a meaningful way. It is, however, the modern-day battlefield where the voting rights movement was born.
Hitler was no inexorable product of a German 'special path', no logical culmination of long-term trends in specifically German culture and ideology. Nor was he a mere 'accident' in the course of German history.
Also, what mountains of dead ashes, wreck and burnt bones, does assiduous pedantry dig up from the past time and name it History.
Remember, remember, the Fifth of November, the Gunpowder Treason and Plot. I know of no reason why the Gunpowder Treason should ever be forgot... But what of the man? I know his name was Guy Fawkes and I know, in 1605, he attempted to blow up the Houses of Parliament.
Our national history cannot be national if, in the near future, one in three young adults feels their stories remain untold, if this country's long global history of empire and interconnections is marginalised and if the historical reality of race is rendered almost invisible.
