Quote from ‘Sketch of Dichotomic Mathematics’
Belief does not principally consist in any particular act of thought, but in a habit of thought and a conduct. A man does not necessarily believe what he thinks he believes. He only believes what he deliberately adopts and is ready to make a habit of conduct.
