Apparatus Quotes - page 4
For want of the apparatus of propositional functions, many logicians have been driven to the conclusion that there are unreal objects. It is argued, e.g., by Meinong, that we can speak about "the golden mountain," "the round square," and so on; we can make true propositions of which these are the subjects; hence they must have some kind of logical being, since otherwise the propositions in which they occur would be meaningless. In such theories, it seems to me, there is a failure of that feeling for reality which ought to be preserved even in the most abstract studies. Logic, I should maintain, must no more admit a unicorn than zoology can; for logic is concerned with the real world just as truly as zoology, though with its more abstract and general features.
Bertrand Russell
More generally, the hidden variable account of a given system becomes entirely different when we remember that it has undoubtedly interacted with numerous other systems in the past and that the total wave function will certainly not be factorable. The same effect complicates the hidden variable account of the theory of measurement, when it is desired to include part of the 'apparatus' in the system. Bohm of course was well aware of these features of his scheme, and has given them much attention. However, it must be stressed that, to the present writer's knowledge, there is no proof that any hidden variable account of quantum mechanics must have this extraordinary character. It would therefore be interesting, perhaps, to pursue some further 'impossibility proofs,' replacing the arbitrary axioms objected to above by some condition of locality, or of separability of distant systems.
John Stewart Bell
While our view of the world is filtered through our senses, evolution has, by and large, molded those senses to perceive the world accurately, for there's a severe penalty to be paid for seeing things wrongly. That holds not only for the external environment, but also for the character of others. Without accurate perceptions, we couldn't find food, avoid predators and other dangers, or form harmonious social groups. And following those perceptions is indeed the pursuit of "true beliefs”: beliefs based on evidence. Natural selection doesn't mold true beliefs; it molds the sensory and neural apparatus that, in general, promotes the formation of true beliefs.

My father, William C. Boulding, was a working plumber in business for himself. At the back of the house was the yard, a corrugated iron shed full of pipes, wrenches, and blow torches, and other mysterious and rather frightening apparatus. He had two faithful employees, Billy Fox, who was moody and regarded as a little queer, and Billy Sankey, who was short and cheerful. They and my father always smelled strongly of some kind of grease. My father was a gentle man. I never I never heard his voice raised in anger. He had had a very hard childhood. His father died soon after he was born; his mother married again, a man known in the family legends as "Pa Hardacre," about whom endless stories were told. He was a bigamist. He drove my father out of the house at the age of twelve to earn his own living on the streets of Liverpool. He constantly mistreated my half-aunts, Ethel and Rosie. He died before I was born, but my mother's accounts of him sounded like something out of Dickens.
