To me this is the most important possession anyone has. If you let anyone else tell you what beliefs you should have then it diminishes you as a person. Whilst your beliefs must be compatible with society and others being able to hold their own beliefs you should not sacrifice more freedom of expression than you have to.
When I am teaching one of the most common complaints is why don't you tell us the answers. Well I can to this question but that does not mean that this question will be the one you want to answer tomorrow, or that anyone will ask this sort of question in the future. The same is true of belief how can anyone tell you what to believe?
What is ironic is that the great religious and humanist thinkers emphasized this. Jesus told his disciples that the church was built from them and not the buildings and the priests. Buddha told his followers not to right down his teachings and that each person had to find his own path to Nirvana. Sadly disciple are disciples so they follow and do not understand. Even the humanists have high priests who say what to believe. Santayana had this idea at the start of the last century that humanism would prevail and that everyone would find their own beliefs and their own God. His humanist disciples want to make us all believe there is no God.
I am pragmatic if I want a God then that is my God and it is what I want for me, it is God created as I want it, if I want it. But I will not listen to priests or humanist priests who want to tell me what to believe.
