Here is a quote by Henry A. Wallace.
" It may be shocking to some people in this country to realize that, without meaning to do so, they hold views in common with Hitler when they preach discrimination against other religious, racial, or economic groups."
Oedipus' self-inflicted blindness symbolizes his foolishness and inability to see clearly what stood before him. Famed for his commonsense and clear thinking, Oedipus has been revealed all too human. Blinding himself is his way of taking responsibility for his part in his father's death and a symbol of new found wisdom. ;)
