“Nothing ought to be posited without a reason given, unless it is self-evident or known by experience or proved by the authority of Sacred Scripture.”
An interesting post with a good point: “But we should also remember that nature is not parsimonious at all.”
However, I’m not sure if anyone cares what Ockham really said. Ockham’s razor is generally formally understood as: “entia non sunt multiplicanda praeter necessitatem (entities must not be multiplied beyond necessity)” (see: Wiki).
He was mediaeval, and probably included god, etc, etc. But the razor remains a good tool, and it really comes down to the “beyond necessity.”
Any bricoleur knows that the razor is not the rule.
