Quotation of the day

From Ludwig Boltzmann
The most ordinary things are to philosophy a source of insoluble puzzles. With infinite ingenuity it constructs a concept of space or time and then finds it absolutely impossible that there be objects in this space or that processes occur during this time... the source of this kind of logic lies in excessive confidence in the so-called laws of thought.
Quoted in B McGuinness, Ludwig Boltzmann, Theoretical Physics and Philosophical Problems, (Dordrecht, 1974) 64.
