"...You can only be free if I am free" - Clarence Darrow

Mill and Marx touched an issue of freedom that is contingent on how much the state put force on you or how much you can intervene to revolt for it. These are two opposite stances that represent passive and active factors of individual approach toward freedom. As Mill claims freedom is our right, thus we do not really bother if the state does not bother us, whereas Marx points out at our involvement and constant vigilance because freedom is not guarantee all the time.
We cannot be fully free because we have a certain limitation in forms of laws, regulations and personal commitments that are imposed to us due to the fact that we are social beings, meaning there are others to consider. Freedom is only attained when we are able to detach ourselves from the outside world and immerse in our own thoughts that liberates our individuality.
Freedom is something that we all want to protect and sustain, however we are easily forget about it and become passive until it is necessary to get involved in case of injustice or other form of slavery.
Therefore, freedom should be always cherished in reference to the universal principle of every human being.
Mill and Marx pointed very important aspect of freedom, as a right and as a force.
