ABSTRACT
There are hazards to thinking too deeply about something, as this children’s poem illustrates.
Philosophy relies on reason to make sense of things.
One problem with pre-scientific beliefs in magic and sympathetic influences between things is the problem of distinguishing coincidences from cause-and-effect relations. ‘‘Believing is seeing.’’ If you believe something strongly enough, you may see all sorts of confirmations of the belief even when they aren’t there.
