Ask yourself whether you have earned the right to have an opinion. Opinions are easy to produce, so bad ones abound. Knowing that you don't know something is nearly as valuable as knowing it. The worst situation is thinking you know something when you don't.
As soon as a thought or word becomes a tool, one can dispense with actually 'thinking' it, that is, with going through the logical acts involved in verbal formulation of it. As has been pointed out, often and correctly, the advantage of mathematics the model of all neo-positivistic thinking lies in just this 'intellectual economy. ' Complicated logical operations are carried out without actual performance of the intellectual acts upon which the mathematical and logical symbols are based. . . . Reason. . . becomes a fetish, a magic entity that is accepted rather than intellectually experienced.
