Sir Thomas Aquinas was a 13th century monk who created the Natural Law theory. He believed there were 7 things that humans needed to do in order to fulfil their purpose, he called these the primary precepts. The secondary precepts derived from these are absolute deontological laws that we should live by. He said that by doing these things we will fulfil our purpose and achieve happiness.
Aquinas’ studied Aristotle’s four causes. He especially focused on the final cause (purpose). Aquinas thought that the purpose of all humans is to lead a fulfilling life by following the primary and secondary precepts.
