The acquisition of the most elementary truth does not devolve upon the individual alone: it is pre-effected in the development of the race.
Personally, people know themselves very poorly.Ernst Mach
I know of nothing more terrible than the poor creatures who have learned too much. Instead of the sound powerful judgement which would probably have grown up if they had learned nothing, their thoughts creep timidly and hypnotically after words, principles and formulae, constantly by the same paths. What they have acquired is a spider's web of thoughts too weak to furnish sure supports, but complicated enough to provide confusion.Ernst Mach
Not bodies produce sensations, but element-complexes (sensation-complexes) constitute the bodies. When the physicist considers the bodies as the permanent reality, the `elements' as the transient appearance, he does not realise that all `bodies' are only mental symbols for element-complexes (sensation-complexes)Ernst Mach
What Mach calls a thought experiment is of course not an experiment at all. At bottom it is a grammatical investigation.Ernst Mach
The history of the development of mechanics is quite indispensable to a full comprehension of the science in its present condition. It also affords a simple and instructive example or the processes by which natural science generally is developed.Ernst Mach
The acquisition of the most elementary truth does not devolve upon the individual alone: it is pre-effected in the development of the race.Ernst Mach
In reality, the law always contains less than the fact itself, because it does not reproduce the fact as a whole but only in that aspect of it which is important for us, the rest being intentionally or from necessity omitted.Ernst Mach
