Ethical solipsism is a form of personal morality that holds that no other moral judgement exists or matters apart from one's own individual moral judgement. It is related to ethical egoism but with the difference that the ethical egoist thinks that individuals should abide by the morality of social order to the extent that it is in their own self-interest to do so.
Due to the solipsistic uncertainty regarding the existence of external beings, it is possible for the ethical solipsist to adhere to external moral standards, for other beings may be real and conscious.
It has been suggested by Wojciech Załuski that a true ethical solipsist will be an adult who will belittle the reality of other people and show a negative ethical evaluation; this could include extreme narcissism or egotism and the Marquise de Sade’s philosophie de libertinage may be one example of this. [1]
Sami Pihlström has suggested that an ethical solipsist will have an attitude of both humility and responsibility for others. [2]
In ethical philosophy, ethical egoism is the normative position that moral agents ought to act in their own self-interest. It differs from psychological egoism, which claims that people can only act in their self-interest. Ethical egoism also differs from rational egoism, which holds that it is rational to act in one's self-interest. Ethical egoism holds, therefore, that actions whose consequences will benefit the doer are ethical.
Ethical naturalism is the meta-ethical view which claims that:
Individualism is the moral stance, political philosophy, ideology, and social outlook that emphasizes the intrinsic worth of the individual. Individualists promote realizing one's goals and desires, valuing independence and self-reliance, and advocating that the interests of the individual should gain precedence over the state or a social group, while opposing external interference upon one's own interests by society or institutions such as the government. Individualism makes the individual its focus, and so starts "with the fundamental premise that the human individual is of primary importance in the struggle for liberation".
In metaphilosophy and ethics, metaethics is the study of the nature, scope, and meaning of moral judgment. It is one of the three branches of ethics generally studied by philosophers, the others being normative ethics and applied ethics.
In metaethics, the naturalistic fallacy is the claim that it is possible to define good in terms of merely described entities, properties, or processes such as pleasant, desirable, or fitness. The term was introduced by British philosopher G. E. Moore in his 1903 book Principia Ethica.
Normative ethics is the study of ethical behaviour and is the branch of philosophical ethics that investigates questions regarding how one ought to act, in a moral sense.
Morality is the categorization of intentions, decisions and actions into those that are proper, or right, and those that are improper, or wrong. Morality can be a body of standards or principles derived from a code of conduct from a particular philosophy, religion or culture, or it can derive from a standard that is understood to be universal. Morality may also be specifically synonymous with "goodness", "appropriateness" or "rightness".
Moral relativism or ethical relativism is used to describe several philosophical positions concerned with the differences in moral judgments across different peoples and cultures. An advocate of such ideas is often referred to as a relativist.
Solipsism is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind.
In developmental psychology and moral, political, and bioethical philosophy, autonomy is the capacity to make an informed, uncoerced decision. Autonomous organizations or institutions are independent or self-governing. Autonomy can also be defined from a human resources perspective, where it denotes a level of discretion granted to an employee in his or her work. In such cases, autonomy is known to generally increase job satisfaction. Self-actualized individuals are thought to operate autonomously of external expectations. In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine.
Ethical subjectivism is the meta-ethical view which claims that:
Lawrence Kohlberg's stages of moral development constitute an adaptation of a psychological theory originally conceived by the Swiss psychologist Jean Piaget. Kohlberg began work on this topic as a psychology graduate student at the University of Chicago in 1958 and expanded upon the theory throughout his life.
In metaphysics, Metaphysical solipsism is the variety of idealism which asserts that nothing exists externally to this one mind, and since this mind is the whole of reality then the "external world" was never anything more than an idea. It can also be expressed by the assertion "there is nothing external to these present experiences", in other words, no reality exists beyond whatever is presently being cognized by that one mind. The aforementioned definition of solipsism entails the non-existence of anything presently unperceived including the external world, causation, other minds, the past or future, and a subject of experience. Despite their ontological non-existence, these entities may nonetheless be said to "exist" as useful descriptions of the various experiences and thoughts that constitute 'this' mind
In epistemology, epistemological solipsism is the claim that one can only be sure of the existence of one's mind. The existence of other minds and the external world is not necessarily rejected but one can not be sure of its existence.
The Methods of Ethics is a book on ethics first published in 1874 by the English philosopher Henry Sidgwick. The Stanford Encyclopedia of Philosophy indicates that The Methods of Ethics "in many ways marked the culmination of the classical utilitarian tradition." Noted moral and political philosopher John Rawls, writing in the Forward to the Hackett reprint of the 7th edition, says Methods of Ethics "is the clearest and most accessible formulation of ... 'the classical utilitarian doctrine'". Contemporary utilitarian philosopher Peter Singer has said that the Methods "is simply the best book on ethics ever written."
Science of morality may refer to various forms of ethical naturalism grounding morality and ethics in rational, empirical consideration of the natural world. It is sometimes framed as using the scientific approach to determine what is right and wrong, in contrast to the widespread belief that "science has nothing to say on the subject of human values".
The Moral Landscape: How Science Can Determine Human Values is a 2010 book by Sam Harris, in which he promotes a science of morality and argues that many thinkers have long confused the relationship between morality, facts, and science. He aims to carve a third path between secularists who say morality is subjective and religionists who say that morality is dictated by God and scripture.
On the Genealogy of Morality: A Polemic is an 1887 book by German philosopher Friedrich Nietzsche. It consists of a preface and three interrelated treatises that expand and follow through on concepts Nietzsche sketched out in Beyond Good and Evil (1886). The three treatises trace episodes in the evolution of moral concepts with a view to confronting "moral prejudices", specifically those of Christianity and Judaism.
Behavioral ethics is a field of social scientific research that seeks to understand how individuals behave when confronted with ethical dilemmas. It refers to behavior that is judged within the context of social situations and compared to generally accepted behavioral norms.
Moral Inquiries on the Situation of Man and of Brutes is an 1824 book by Lewis Gompertz, an early animal rights advocate and vegan. The book argues that animals, like humans, are sentient beings capable of experiencing pain and pleasure, and thus deserve moral consideration. He critiques the exploitation of animals for labour, food, and clothing, condemning practices such as slaughter, hunting, and scientific experimentation. He also addresses the suffering of wild animals, suggesting that even in nature, animals face hardships such as hunger and predation. Gompertz promotes a vegan lifestyle, rejecting not only meat but also animal products like milk, eggs, leather, and wool, and questions the justification for using animals in any way that causes harm. His work critiques existing laws like Martin's Act and the Vagrancy Act, calling for stronger legal protections for animals and laying the groundwork for modern animal rights movements.
