“Nearly everywhere---often even when dealing with purely technical problems---instead of thinking, one merely takes sides: for or against. Such a choice replaces the activity of the mind. This is an intellectual leprosy; it originated in the political world and then spread through the land, contaminating all forms of thinking. This leprosy is killing us; it is doubtful whether it can be cured without first starting with the abolition of all political parties. . . . When joining the party, [man] therefore also endorses a number of positions which he does not know. In fact, he submits his thinking to the authority of the party. . . . If a man were to say, as he applied for his party membership card, 'I agree with the party on this and that question; I have not yet studied its other positions and thus I entirely reserve my opinion, pending further information,' he would probably be advised to come back at a later date.”
