All restraints upon man's natural liberty, not necessary for the simple maintenance of justice, are of the nature of slavery, and differ from each other only in degree.
Interpretation
Freedom should only be limited when necessary for justice; otherwise, limitations resemble slavery.
This quote by Lysander Spooner emphasizes that any restrictions placed on an individual's natural rights and freedoms, unless essential for maintaining justice, are a form of oppression akin to slavery. Spooner argues that the only legitimate constraints on personal liberty are those that prevent harm to others, and that any additional restrictions are unnecessary and unjustifiable.
In practice
During a lecture on civil liberties, one can use this quote to highlight the importance of freedom in society.
The principle that the majority have a right to rule the minority, practically resolves all government into a mere contest between two bodies of men, as to which of them shall be masters, and which of them slaves; a contest, that-however bloody-can, in the nature of things, never be finally closed, so long as man refuses to be a slave.
For a government to declare a vice to be a crime, and to punish it as such, is an attempt to falsify the very nature of things. It is as absurd as it would be to declare truth to be falsehood, or falsehood truth.
And the men who loan money to governments, so called, for the purpose of enabling the latter to rob, enslave, and murder their people, are among the greatest villains that the world has ever seen. And they as much deserve to be hunted and killed (if they cannot otherwise be got rid of) as any slave traders, robbers, or pirates that ever lived.
A married woman has the same natural right to acquire and hold property, and to make all contracts that she is mentally competent to make reasonably, as has a married man, or any other man.
Slavery, if it can be legalized at all, can be legalized only by positive legislation. Natural law gives it no aid. Custom imparts to it no legal sanction.
Those who deny the right of a jury to protect an individual in resisting an unjust law of the government, deny him all defence whatsoever against oppression.
The liberty of man consists solely in this, that he obeys the laws of nature because he has himself recognized them as such, and not because they have been imposed upon him externally by any foreign will whatsoever, human or divine, collective or individual.
The beauty of our system is that it isolates everybody. Each person is sitting alone in front of the tube, you know. It's very hard to have ideas or thoughts under those circumstances. You can't fight the world alone.
Odors have an altogether peculiar force, in affecting us through association; a force differing essentially from that of objects addressing the touch, the taste, the sight or the hearing.
All over Harlem, Negro boys and girls are growing into stunted maturity, trying desperately to find a place to stand; and the wonder is not that so many are ruined but that so many survive.
Freedom is the right to tell people what they do not want to hear.
I was not wounded in any part of my body, but I had never experienced such intense pain, such a ripping of the nerves, such an ache of the heart.
