Are Complex Number Less Real Than Integers?
Platonists generally believe so; as mathematician Leopold Kronecker once said:
God created the integers; the rest is the work of man.
Platonists hold that various mathematical constructs have different degrees of physical existence, some more real than others. Well known platonists include Kurt Godel and Sir Roger Penrose.
How come platonism isn’t as popular it’s used to be?
