Defined Quote by Henri Poincare
“For a long time the objects that mathematicians dealt with were mostly ill-defined; one believed one knew them, but one represented them with the senses and imagination; but one had but a rough picture and not a precise idea on which reasoning could take hold.”

![“The self is defined psychologically as the psychic totality of the individual. Anything that a [person] postulates as being a greater totality than [oneself] can become a symbol of the self. For this reason the symbol of the self is not always as total as the definition would require.” quote by Carl Jung](https://sms4smile.com/quotes/img-quotes/251/carl-jung-274_defined_the-self-is-defined-psychologically-as-t_7148.jpg)
