quote from Hardy

Bruno quotes: "Of this reality, as I explained […], I take a 'realistic" view. At any rate (and this is my main point) this realistic view is much more plausible of mathematical than of physical reality, because mathematical objects are so much more what they seem. A chair or a star is not in
