The concepts of right and obligation, of lawful and unlawful, and of good and bad are the most focal ones in the philosophy of value, particularly in the philosophy of law and ethics. They are mostly discussed from epistemological aspects. Our main question in this survey is of the origin of legal and ethical propositions. Do they directly relate to an objective external reality that determines their truth; or are they only based on the intentions and the purposes of the people who stipulate them? Legal and moral naturalists have chosen the first explanation with various interpretations, and conventionalists have tried to prove the second one. In this study, configuration and construction are regarded as mental construct entities in practical philosophy and the theory of conventionalism is shown to be more reasonable and defensible.
