There are many common examples to illustrate the point. Consider your existence for instance like that of a tree, that has its roots firmly set in the earth, that it cannot move around like animals, but as the wind blows its branches can twist and flex, and when gentle breeze glides through its leave dance and wave in response. This is just as much freedom a tree needs to survive, and there is just as much freedom denied to it for the good of its own.
The answer to the question of free will therefore is not a simple and straightforward; it is not in black and white. This is what some people want to have when they want to know absolutely, i.e. do we have freedom of will, meaning, do we have absolute freedom of will? The answer, in reality, is the simple fact of our existence, easy to observe, that we have some freedom but never absolute.
The matter of being free, i.e. to think and to act, and therefore to live our lives, is important to us. We like to know if our thoughts, the motives behind our actions are purely our own, and if the life we have, that we make so much effort to improve and live to the best of our ability, is purely our personal enterprise?
The problem then is this. That when we learn, and try to accept, the fact that we are only partially free, then we want to know what power or agency aside ourselves is there to have a stake in determining the course of our lives and the consequences thereafter. We all search for the answer to this question, and we all eventually find our own answers. Some people find the answer to this question in God, some see it in the humanity that they are but a little part of, some even put their faith, and quite fatefully so, in the randomness of opportunity and chance.
