This isn't true. If a plane flies like a bird and you only need it for flying it doesn't then follow that a plane is a bird "for all intents and purposes".
- i-use-nixos-btw 4y agoThe emphasis on “for all intents and purposes” is important. If you specify requirements you specify them for your intent and for your purpose. Requiring that something fly and that something be a plane are two different things with only minor overlap. If all you require is something that flies, then a dragonfly matches your requirements exactly as much as an apache helicopter does.
