There are many kinds of freedom. All of which are rare.
There is financial freedom, which few people know. There is social freedom—the freedom to be completely yourself, about which ee cummings said:
“It takes courage to grow up and become who you really are. To be nobody but yourself in a world which is doing its best day and night to make you like everybody else means to fight the hardest battle which any human being can fight and never stop fighting.”
There are civic freedoms, which vary from state to state, country to country, and have never found the balance between protecting the many and protecting the few. There are some people who do not have freedom to love who or what they want.
It seems to me, however, that freedom of thought is the ultimate freedom. Being free to think. Or, more accurately, choosing to think for yourself. Very few, if any, people do this. Most people follow a party line, or the indoctrination they have heard since birth. Or they follow the cultural norms—they believe what they are expected to believe without ever questioning it.
Once you do begin to question the beliefs you are supposed to hold, you are in for some distress and danger. In spite of that, though, freedom inside your own head is the ultimate, the most complete freedom available.
