"Idolatry is in a man's own thought, not in the opinion of another"

John Selden's quote speaks to the concept that idolatry is an individual matter, and is not determined by the viewpoint of another. This suggests that idolatry refers personal belief and conviction, and is not something that can be troubled somebody by another individual. It implies that a person's own ideas and beliefs are the only ones that can genuinely identify whether somebody is engaging in idolatry. This quote also recommends that one's own opinion is the only one that matters when it comes to matters of faith and religious beliefs. It implies that no one else can determine what somebody believes, which it is eventually up to the individual to decide what they believe and how they practice their faith. Eventually, this quote talks to the concept that a person's own thoughts and beliefs are the only ones that can really figure out whether someone is taking part in idolatry.
