Natural law is a system of law based on a close observation of human nature, and based on values intrinsic to human nature that can be deduced and applied independently of positive law. According to the theory of law called jusnaturalism, all people have inherent rights, conferred not by act of legislation but by "God, nature, or reason." Natural law theory can also refer to "theories of ethics, theories of politics, theories of civil law, and theories of religious morality."
Political philosophy or political theory is the philosophical study of government, addressing questions about the nature, scope, and legitimacy of public agents and institutions and the relationships between them. Its topics include politics, liberty, justice, property, rights, law, and the enforcement of laws by authority: what they are, if they are needed, what makes a government legitimate, what rights and freedoms it should protect, what form it should take, what the law is, and what duties citizens owe to a legitimate government, if any, and when it may be legitimately overthrown, if ever.
In moral and political philosophy, the social contract is a theory or model that originated during the Age of Enlightenment and usually, although not always, concerns the legitimacy of the authority of the state over the individual.
Reason is the capacity of applying logic consciously by drawing conclusions from new or existing information, with the aim of seeking the truth. It is associated with such characteristically human activities as philosophy, science, language, mathematics, and art, and is normally considered to be a distinguishing ability possessed by humans. Reason is sometimes referred to as rationality.
In philosophy, rationalism is the epistemological view that "regards reason as the chief source and test of knowledge" or "any view appealing to reason as a source of knowledge or justification", often in contrast to other possible sources of knowledge such as faith, tradition, or sensory experience. More formally, rationalism is defined as a methodology or a theory "in which the criterion of truth is not sensory but intellectual and deductive".
Will, within philosophy, is a faculty of the mind. Will is important as one of the parts of the mind, along with reason and understanding. It is considered central to the field of ethics because of its role in enabling deliberate action.
The term Homo economicus, or economic man, is the portrayal of humans as agents who are consistently rational and narrowly self-interested, and who pursue their subjectively defined ends optimally. It is a word play on Homo sapiens, used in some economic theories and in pedagogy.
Human potential is the capacity for humans to improve themselves through studying, training, and practice, to reach the limit of their ability to develop aptitudes and skills. "Inherent within the notion of human potential is the belief that in reaching their full potential an individual will be able to lead a happy and more fulfilled life".
In philosophy, economics, and political science, the common good is either what is shared and beneficial for all or most members of a given community, or alternatively, what is achieved by citizenship, collective action, and active participation in the realm of politics and public service. The concept of the common good differs significantly among philosophical doctrines. Early conceptions of the common good were set out by Ancient Greek philosophers, including Aristotle and Plato. One understanding of the common good rooted in Aristotle's philosophy remains in common usage today, referring to what one contemporary scholar calls the "good proper to, and attainable only by, the community, yet individually shared by its members."
Self-deception is a process of denying or rationalizing away the relevance, significance, or importance of opposing evidence and logical argument. Self-deception involves convincing oneself of a truth so that one does not reveal any self-knowledge of the deception.
A need is dissatisfaction at a point of time and in a given context. Needs are distinguished from wants. In the case of a need, a deficiency causes a clear adverse outcome: a dysfunction or death. In other words, a need is something required for a safe, stable and healthy life while a want is a desire, wish or aspiration. When needs or wants are backed by purchasing power, they have the potential to become economic demands.
Agency is the capacity of an actor to act in a given environment. It is independent of the moral dimension, which is called moral agency.
Selfishness is being concerned excessively or exclusively for oneself or one's own advantage, pleasure, or welfare, regardless of others.
Discourse on the Origin and Basis of Inequality Among Men, also commonly known as the "Second Discourse", is a 1755 treatise by philosopher Jean-Jacques Rousseau, on the topic of social inequality and its origins. The work was written in 1754 as Rousseau's entry in a competition by the Academy of Dijon, and was published in 1755.
Moral agency is an individual's ability to make moral choices based on some notion of right and wrong and to be held accountable for these actions. A moral agent is "a being who is capable of acting with reference to right and wrong."
Human nature is a concept that denotes the fundamental dispositions and characteristics—including ways of thinking, feeling, and acting—that humans are said to have naturally. The term is often used to denote the essence of humankind, or what it 'means' to be human. This usage has proven to be controversial in that there is dispute as to whether or not such an essence actually exists.
Common sense is sound, practical judgement concerning everyday matters, or a basic ability to perceive, understand, and judge in a manner that is shared by nearly all people.
Sources of the Self: The Making of the Modern Identity is a work of philosophy by Charles Taylor, published in 1989 by Harvard University Press. It is an attempt to articulate and to write a history of the "modern identity".
The philosophy of human rights attempts to examine the underlying basis of the concept of human rights and critically looks at its content and justification. Several theoretical approaches have been advanced to explain how and why the concept of human rights developed.
Culture and social cognition is the relationship between human culture and human cognitive capabilities. Cultural cognitive evolution proposes that humans’ unique cognitive capacities are not solely due to biological inheritance, but are in fact due in large part to cultural transmission and evolution. Modern humans and great apes are separated evolutionarily by about six million years. Proponents of cultural evolution argue that this would not have been enough time for humans to develop the advanced cognitive capabilities required to create tools, language, and build societies through biological evolution. Biological evolution could not have individually produced each of these cognitive capabilities within that period of time. Instead, humans must have evolved the capacity to learn through cultural transmission. This provides a more plausible explanation that would fit within the given time frame. Instead of having to biologically account for each cognitive mechanism that distinguishes modern humans from previous relatives, one would only have to account for one significant biological adaptation for cultural learning. According to this view, the ability to learn through cultural transmission is what distinguishes humans from other primates. Cultural learning allows humans to build on existing knowledge and make collective advancements, also known as the “ratchet effect”. The ratchet effect simply refers to the way in which humans continuously add on to existing knowledge through modifications and improvements. This unique ability distinguishes humans from related primates, who do not seem to build collaborative knowledge over time. Instead, primates seem to build individual knowledge, in which the expertise of one animal is not built on by others, and does not progress across time.
