Professor Kreeft, how can angels be anything at all if they have no bodies?
‘We can’t imagine a spirit without a body. We can conceive of all sorts of things we can’t imagine, such as time, and relationships, and numbers. You can imagine a just person, but you can’t imagine Justice. You can imagine two apples, but you can’t imagine twoness. You can imagine a body, but not a spirit, or mind, or soul. You can’t imagine your self, only your body. Many people disbelieve in angels because they disbelieve in spirit. They believe only matter exists. The technical name for this philosophy is materialism. Materialism, the denial of spirit or soul, is a faith. It is not scientific, for there can be no scientific proof against something that cannot appear as data for any scientific instrument. Materialism is not commonsensical, for fewer than one percent of all men in history have believed it. Materialism is not based on experience, for we experience our minds as well as our bodies. Humans are the lowest (least intelligent) of spirits and the highest (most intelligent) of animals. We are rational animals.’
