|Empiricism: a branch within epistemology which assumes that sensory perception is fundamental for setting up claims and theories. The opposite position, rationalism, assumes that even purely logical knowledge and conclusions from this knowledge may be sufficient for the building of theories. See also logical positivism, instrumentalism, rationalism, epistemology, theories, foundation, experiments, > inferentialism, knowledge, experience, science._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Empiricism/Definition/Mach/Feynman: you can only define what you can measure.
FeynmanVsMach: whether a thing is measurable or not, cannot be decided a priori solely by reasoning! It can only be decided in experiments.
((s) VsFeynman: but doesn't it need to be defined before the experiment?)
Feynman: it is clear that absolute speed has no meaning. Whether or not it can be defined is the same as the problem, whether you can prove if you are moving or not!_____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
