Document Summary
Logicism: idea that thinking is identical to performing logical operations. If logic is thinking, then machines doing logic, are thinking machines. Implementation level: what physical mechanisms do you need for the architecture. Animism: assignment of lifelike qualities to inanimate moving object. Tortoises: autonomous robot, mimic life, used to investigate possibility that organisms were simple devices governed by cybernetic principles. Invented in 20th century with 17th century ideas of logic & math. Goal was to move philosophy into math. Developed sets, x y z to represent elements, operation signs (+ -), Secondary propositions: statement about a proposition that could either be true/false. Attempt to simplify and improve booles logic lead to binary logic: problems like. + defined as exculsive or, ie one intersection is empty. But what is x + x ? no answer. Jevon corrected by interpreting addition as inclusive or, making x + x =x.
