In the first physics lecture I ever visited, the professor shortly demonstrated the fallibility of our senses with a spinning disc optical illusion to justify the use of measurement devices. He didn't say a word about where these measurement devices “come from”.
If we can't intuit certain propositions by reason alone (i.e. for a simple clock, that identical pendulums will behave in the same way – otherwise, how could a comparison ever be made to get to Galileo's result that the period of a pendulum is independent of the amplitude of its swing?), how can we construct measurement devices? How can we do it, if we assume that scientific observation presupposes that we have and can use measurement devices?
Was there a philosopher who pointed to measurement devices as an argument for rationalism? And how could an empiricist explain that the construction of measurement devices is compatible with strict empiricism?
