We cannot create observers by saying "observe," but by giving them the power and the means for this observation and these means are procured through education of the senses
Maria Montessori
The observation of others is coloured by our inability to observe ourselves impartially. We can never be impartial about anything until we can be impartial about our own organism.
A. R. Orage
This inescapable duty to observe oneself: if someone else is observing me, naturally I have to observe myself too; if none observe me, I have to observe myself all the closer
Franz Kafka
