We often think of law as something abstract, whereas nothing could be more concrete. It can be seen as a set of legal charges and fields analogous to electrostatic charges and fields. The human person is also comparable to a positive charge. The right of ownership, for example, is a positive charge that ensures the protection of a property by repressing a non-owner who wishes to access the enjoyment or possession of this property without being authorized to do so. A contract is a set of dipoles by which an obligation, with a positive charge, obliges a debtor to deliver a good or service to a creditor holding a claim, with a negative charge. The law is a set of positive charges placed on a ruler, whose parallel field forces will govern a population.
