Liability without fault

It is a general principle of our law that there is no individual liability for an act which ordinary human care and foresight could not guard against. It is also a general principle of the same law that a loss from any cause purely accidental must rest where it chances to fall. But behind and above these general principles which the law recognizes as ordinarily prevailing, there lies the legislative power, which, in the absence of organic restraint, may, for the general welfare of society, impose obligations and responsibilities otherwise nonexistent.
