As a rule it is not the alleged reasons which lead people to their statements. Beneath and behind the reasons, it is the habits of thought which they have acquired, and which determine their whole way of feeling. While they put forward reasons, they are only masking feelings that are instinctive with thoughts that are habitual. Thus often, not only is the wish father to the thought, but all the feelings and habits and ways of thinking are parents of the thoughts. A man who knows life, knows how little possibility there is of convincing people by logical grounds and arguments. That which decides in the soul is far deeper than the logical reasons.
