“Orthodoxy means not thinking--not needing to think. Orthodoxy is unconsciousness.”― George Orwell, 1984“It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living. It is clear also that thought is not free if all the arguments on one side of a controversy are perpetually presented as attractively as possible, while the arguments on the other side can only be discovered by diligent search.”― Bertrand Russell, Sceptical Essays
