“If you belong to the prickly type, you hope that the ultimate constituent of matter is particles. If you belong to the gooey type, you hope it's waves. If you are prickly, you're a classicist. And if you’re gooey, you're a romanticist. And going back into medieval philosophy, if you’re prickly, you're a nominalist. If you're gooey, you're a realist. And so it goes. But we know very well that this natural universe is neither prickles nor goo exclusively. It's gooey prickles and prickly goo.”

— Alan Watts, Tao of Philosophy
