The mood Shakespeare evokes through these lines is one of despair. He is in despair because he is calling out to a "deaf heaven." He knows his cries are useless because they will go unheard or unanswered. He is also feeling unlucky as a result of his fate, feeling as though he is not something more because that fate has held him back or beat him down.
Education increases freedom, as does community. A guide and a path of life grants freedom because it enables one to flourish. Anything that stunts possibility enslaves us.
