natural law

Avicenna has aimed to establisha harmonized philosophical system that incorporates logic, epistemology, metaphysics, natural philosophy, and other types of knowledge. Although he has not directly written anything about the metaphysical foundations of science, we believe that there are some implications in his philosophy that could be considered astruthmakers of scientific propositions. As natural law is significantly correlated to “experiment”, we will first discuss the epistemological aspect of experiments in Avicennian philosophy. He believes that the observation of a repeated event could lead us to a causal relationship due to the fact that accidental events are neither permanent nor frequent. Following that, the logical approach which corresponds to this epistemology will be introduced. As Avicenna’s logic does not directly consider such an approach, we are to derive it from apparently disconnected chapters and then formulate them. It will be indicated that Avicenna has been aware of the differences between propositions that merely refer to existent instances and ones that consider the nature of instances. The latter obviously could refer to both existent instances and hypothetical instances. Finally, we present some points in his metaphysics that could establisha metaphysical basis for propositions concerning natural law. In addition, we will indicate that Avicenna’s system is able to justify the counterfactual conditionals that relate to laws of nature.

Universality of common human values embedded in declarations and international treaties supposed to be evident in the international human rights legal system but it does not mean that there were no intellectual discrepancies behind those instruments. Universality of human rights has its roots more than anything on theories of Jhon locke's natural law and Immanuel kant's rational ethics . But one of the earliest philosophers of opposition side against unity of human nature and universal morality at the embryonic stage was Nietzsche . Bringing forth the theory of will to power by adopting a psychological genealogy method Nietzsche distinguished between two moralities: Masters Morality and Slaves Morality . He attributed human rights as slave morality. Slaves revolted with the spirit of resentment and womanish deception against masters then introduced their own qualities as standard and universal . The Rise of Christianity and the Great French Revolution are amongst two biggest examples of such slave revolt in morality. With such a presupposition, trying by any effort to reconcile human rights morals with Nietzschean views seems to be unachievable. While reviewing past philosophical challenges, this article tries to analyze necessity of co-existence both international human rights legal system and Nietzschean world from a new perspective.

Thomas Hobbes's theory of "social contract" provided a new basis for the establishment of the gov-ernment, which had fundamental differences with the theories before it. In such a way that he con-sidered the government "constitutional" and not "natural". According to him, before the govern-ment, people lived in a natural state, which is a kind of a state of war, and according to the natural law and the rule of reason, they should have left this state and entered a state of peace. A state of peace requires the "establishment" of the government to provide security. Based on this, the citizens establish the government through agreement and contract and transfer all their rights to it in order to end the war situation and be the final judge of the affairs. This theory of Hobbes was proposed in the field of religious and political ideological controversies, which its roots go back to the late Mid-dle Ages and the conflict between the church and the kingdom regarding the basis of the legitimacy of the government. On this basis, without paying attention to the context of Hobbes's discussion, it is not possible to get a precise understanding of his theory and intention in the "Social Contract" plan. Our goal in this article is to read Hobbes's theory "context-centered" and we use Quentin Skinner's approach. As a result, our question is, in what context was Thomas Hobbes's "social con-tract" about the basis of government legitimacy formed, and what was his intention in proposing it? Our hypothesis is that Thomas Hobbes, in the field of disputes between the church and the kings, based on the two main theories of the absolute authority of the Pope (controversy of installation) and the divine right of kings, to transition from the state of religious-political wars in England, pro-posed a "social contract" and provided a new basis of legitimacy for the establishment of the state.
