It must then be asked, "Is science 'materialistic'?" The answer to that is "no," because, although many scientists may in fact be materialists, materialism is a metaphysical doctrine and is both inessential to science and independent of its method.
If the purpose of science is to discover the laws of nature, then events that involve the suspension of the laws of nature by that very fact can be no part of science.
Science cannot study a law of nature when such a law is not in operation -- indeed when no law is in operation.
