an innkeeper. In other words, in these cases one was held without regard to fault for injuries incidental to the conduct of certain enterprises or callings and for failure to restrain potentially injurious agencies which one maintained. Modern law has given up both the nominate delicts and quasi-delict, as things of any significance. The French civil code made the idea of Aquilian _culpa_ into a general theory of delictal liability, saying, "Every act of man which causes damage to another obliges him through whose fault it happened to make reparation." In other words, liability is to be based on an act, and it must be a culpable act. Act, culpability, causation, damage, were the elements. This simple theory of liability for culpable causation of damage was accepted universally by civilians until late in the nineteenth century and is still orthodox. Taken up by text writers on torts in the last half of that century, it had much influence in Anglo-American law. But along with this generalization the French code preserved a liability without fault, developed out of the noxal actions, whereby parents and teachers may be held for injuries by minors under their charge, masters for injuries by their apprentices, employers for injuries by employees and those in charge of animals for injuries by such animals. Also it provided an absolute liability for injury by a _res ruinosa_, developed out of the Roman _cautio damni infecti_. In the case of parents, teachers and masters of apprentices, there is only a presumption of fault. They may escape by showing affirmatively that they were without fault and that what happened could not have been prevented by diligence on their part. In the case of employers no excuse is admitted. The liability is absolute. In the case of animals, fault of the victim, inevitable accident and _vis maior_ may be shown affirmatively by way of defence. In the case of a _res ruinosa_ there is no presumption of fault. But if the structure fell or did injury because of a defect of construction or want of repair, the owner is liable absolutely and may not show that he had no notice of the defect and no reason to suspect it, or that it was not in his power to prevent the structure from falling.
