Ethics or moral philosophy is the philosophical study of moral phenomena. It investigates normative questions about what people ought to do or which behavior is morally right. It is usually divided into three major fields: normative ethics, applied ethics, and metaethics.
Euthanasia is the practise of intentionally ending life to eliminate pain and suffering.
Peter Albert David Singer is an Australian moral philosopher who is Emeritus Ira W. DeCamp Professor of Bioethics at Princeton University. Singer's work specialises in applied ethics, approaching the subject from a secular, utilitarian perspective. He wrote the book Animal Liberation (1975), in which he argues for vegetarianism, and the essay "Famine, Affluence, and Morality", which argues the moral imperative of donating to help the poor around the world. For most of his career, he was a preference utilitarian, but he revealed in The Point of View of the Universe (2014), coauthored with Katarzyna de Lazari-Radek, that he had become a hedonistic utilitarian.
A paradox is a logically self-contradictory statement or a statement that runs contrary to one's expectation. It is a statement that, despite apparently valid reasoning from true or apparently true premises, leads to a seemingly self-contradictory or a logically unacceptable conclusion. A paradox usually involves contradictory-yet-interrelated elements that exist simultaneously and persist over time. They result in "persistent contradiction between interdependent elements" leading to a lasting "unity of opposites".
Time travel is the hypothetical activity of traveling into the past or future. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a hypothetical device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time Machine.
The Novikov self-consistency principle, also known as the Novikov self-consistency conjecture and Larry Niven's law of conservation of history, is a principle developed by Russian physicist Igor Dmitriyevich Novikov in the mid-1980s. Novikov intended it to solve the problem of paradoxes in time travel, which is theoretically permitted in certain solutions of general relativity that contain what are known as closed timelike curves. The principle asserts that if an event exists that would cause a paradox or any "change" to the past whatsoever, then the probability of that event is zero. It would thus be impossible to create time paradoxes.
Lucas Bishop is a character appearing in American comic books published by Marvel Comics. Created by writer John Byrne and artist Whilce Portacio, the character first appeared in The Uncanny X-Men #282. Bishop debuted as a member of a mutant police force from a dystopian future of the Marvel Universe Xavier's Security Enforcers (XSE). He traveled to the 20th century and joined the X-Men. The character possesses the ability to absorb energy.
A temporal paradox, time paradox, or time travel paradox, is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time travel or other foreknowledge of the future. While the notion of time travel to the future complies with the current understanding of physics via relativistic time dilation, temporal paradoxes arise from circumstances involving hypothetical time travel to the past – and are often used to demonstrate its impossibility.
Reductio ad Hitlerum, also known as playing the Nazi card, is an attempt to invalidate someone else's argument on the basis that the same idea was promoted or practised by Adolf Hitler or the Nazi Party. Arguments can be termed reductio ad Hitlerum if they are fallacious. Contrarily, straightforward arguments critiquing specifically fascist components of Nazism like Führerprinzip are not part of the association fallacy.
Anders Sandberg is a Swedish researcher, futurist and transhumanist. He holds a PhD in computational neuroscience from Stockholm University, and is currently a senior research fellow at the Future of Humanity Institute at the University of Oxford, and a Fellow at Reuben College.
A physical paradox is an apparent contradiction in physical descriptions of the universe. While many physical paradoxes have accepted resolutions, others defy resolution and may indicate flaws in theory. In physics as in all of science, contradictions and paradoxes are generally assumed to be artifacts of error and incompleteness because reality is assumed to be completely consistent, although this is itself a philosophical assumption. When, as in fields such as quantum physics and relativity theory, existing assumptions about reality have been shown to break down, this has usually been dealt with by changing our understanding of reality to a new one which remains self-consistent in the presence of the new evidence.
Time travel is a common theme in fiction, mainly since the late 19th century, and has been depicted in a variety of media, such as literature, television, film, and advertisements.

Harambe was a western lowland gorilla who lived at the Cincinnati Zoo. On May 28, 2016, a three-year-old boy visiting the zoo climbed under a fence into an outdoor gorilla enclosure where he was violently grabbed and dragged by Harambe. Fearing for the boy's life, a zoo worker shot and killed Harambe. The incident was recorded on video and received broad international coverage and commentary, including controversy over the choice to use lethal force. A number of primatologists and conservationists wrote later that the zoo had no other choice under the circumstances, and that it highlighted the danger of zoo animals near humans and the need for better standards of care.
Animal ethics is a branch of ethics which examines human-animal relationships, the moral consideration of animals and how nonhuman animals ought to be treated. The subject matter includes animal rights, animal welfare, animal law, speciesism, animal cognition, wildlife conservation, wild animal suffering, the moral status of nonhuman animals, the concept of nonhuman personhood, human exceptionalism, the history of animal use, and theories of justice. Several different theoretical approaches have been proposed to examine this field, in accordance with the different theories currently defended in moral and political philosophy. There is no theory which is completely accepted due to the differing understandings of what is meant by the term ethics; however, there are theories that are more widely accepted by society such as animal rights and utilitarianism.
Wild animal suffering is the suffering experienced by non-human animals living outside of direct human control, due to harms such as disease, injury, parasitism, starvation and malnutrition, dehydration, weather conditions, natural disasters, and killings by other animals, as well as psychological stress. Some estimates indicate that these individual animals make up the vast majority of animals in existence. An extensive amount of natural suffering has been described as an unavoidable consequence of Darwinian evolution and the pervasiveness of reproductive strategies which favor producing large numbers of offspring, with a low amount of parental care and of which only a small number survive to adulthood, the rest dying in painful ways, has led some to argue that suffering dominates happiness in nature.
Alasdair Cochrane is a British political theorist and ethicist who is currently Professor of Political Theory in the Department of Politics and International Relations at the University of Sheffield. He is known for his work on animal rights from the perspective of political theory, which is the subject of his two books: An Introduction to Animals and Political Theory and Animal Rights Without Liberation. His third book, Sentientist Politics, was published by Oxford University Press in 2018. He is a founding member of the Centre for Animals and Social Justice, a UK-based think tank focused on furthering the social and political status of nonhuman animals. He joined the Department at Sheffield in 2012, having previously been a faculty member at the Centre for the Study of Human Rights, London School of Economics. Cochrane is a Sentientist. Sentientism is a naturalistic worldview that grants moral consideration to all sentient beings.
During a speech at the Reichstag on 30 January 1939, Adolf Hitler threatened "the annihilation of the Jewish race in Europe" in the event of war:
If international finance Jewry inside and outside Europe should succeed in plunging the nations once more into a world war, the result will be not the Bolshevization of the earth and thereby the victory of Jewry, but the annihilation of the Jewish race in Europe.
The question of how much Germans knew about the Holocaust whilst it was being executed is a matter of debate by historians. With regard to Nazi Germany, some historians argue that it was an open secret amongst the population, whilst others highlight a possibility that the German population were genuinely unaware of the Final Solution. Peter Longerich argues that the Holocaust was an open secret by early 1943, but some authors place it even earlier. However, after the war, many Germans claimed that they were ignorant of the crimes perpetrated by the Nazi regime, a claim associated with the stereotypical phrase "Davon haben wir nichts gewusst".
