In 4th Way discourse, this refers to emotions taking over the functions of thinking. The intellectual center may be taken over by emotions and can be used to construct arguments for defending some decision purely based on emotions. An example would be the fantastic rationalizations true believers have recourse to when defending clearly deceitful, even psychopathic actions of their leaders.
Such 'thinking' is not affected by arguments appealing to reason. The intellectual center is isolated from these by a sort of wall formed by the emotional investment in one's belief. In the event of a long standing practice this can form buffers. Emotional thinking is an example of the wrong work of centers.
