To know oneself, one should assert oneself.
Only the educated are free.
Quality is not an act, it is a habit.
Who seeks shall find.
Leap, and the net will appear.
Problems are not stop signs, they are guidelines.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
Know or listen to those who know.
Be gentle to all and stern with yourself.
You will also allow me to thank the Academy for inviting me to lecture in Stockholm, for its hospitality, and for the opportunity afforded me for admiring the charm of your people and the beauty of your country.
