Enlightenment

Entry 3
Enlightenment is man's emergence from his self-incurred immaturity. Immaturity is the inability to use one's own understanding without the guidance of another. This immaturity is self-incurred if its cause is not lack of understanding, but lack of resolution and courage to use it without the guidance of another. The motto of enlightenment is therefore: Sapere aude! Have courage to use your own understanding!
Dr. Frankenstein do have the knowledge and courage, but I guess his knowledge is not good enough and no one guide him. He even don't have a partner to discus about his experiment.
