An example of metaphor in discussing science:
"Names may begin by suggesting ideas and may not be neutral. But if they are just names they end by being purely conventional tags or identification marks – sometimes very inadequate ones as in the cases of 'real number', 'imaginary number' and 'irrational number', fossils of a mistaken philosophy of mathematics."
