Is freedom a burden?  In many ways, yes.  As the Grand Inquisitor in Dostoevsky's Brothers Karamazov observes, although the freedom which God has given to human beings has led them into great and marvelous discoveries and things, it has also enabled them to venture into and experience existential conundrums and dilemmas that have brought them immense and untold pain.  Friedrich Nietzsche's understood this very well.  If we humans have absolute freedom, where, really, are we going?  Though we live without boundaries, we also live without a point.  What is freedom if everything is free?
     Freedom for freedom's sake is the great challenge of existence:  the marvel is great, but the angst of its emptiness will never end.  But why did it ever begin?
     Yes, the Inquisitor reminds us, be free.  Forget about God and be totally free.  Yet be aware of this:  ultimately, it's all absurdity.
