A brick is a duplicate. It is a physical copy of the idea for a brick. And what’s the big idea? A brick represents unity, a notion of hey, let’s build something together. Like a house, for example. And after you help me build my house, I’ll use a leftover brick and smash you over the skull so that not only will I not have to pay you for your labor, but I won’t have to pay the butcher for meat, because with your sturdy body, I’m sure I’ll have enough food to feed my family for a year.
