Existence is the state of having being or reality in contrast to nonexistence and nonbeing. Existence is often contrasted with essence: the essence of an entity is its essential features or qualities, which can be understood even if one does not know whether the entity exists.
Existentialism is a family of philosophical views and inquiry that prioritize the existence of the human individual, study existence from the individual's perspective, and conclude that, despite the absurdity or incomprehensibility of the universe, individuals must still embrace responsibility for their actions and strive to lead authentic lives. In examining meaning, purpose, and value, existentialist thought often includes concepts such as existential crises, angst, courage, and freedom.
The meaning of life pertains to the inherent significance or philosophical meaning of living. There is no consensus on a definitive answer, and thinking or discourse on the topic is sought in the English language through the question, "What is the meaning of life?". There have been many proposed answers to these questions from many different cultural and ideological backgrounds. The search for life's meaning has produced much philosophical, scientific, theological, and metaphysical speculation throughout history. Different people and cultures believe different things for the answer to this question. Opinions vary on the usefulness of using time and resources in the pursuit of an answer. Excessive pondering can be indicative of, or lead to, an existential crisis.
Objectivism is a philosophical system named and developed by Russian-American writer and philosopher Ayn Rand. She described it as "the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute".
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.
Tawhid is the concept of monotheism in Islam. Tawhid is the religion's central and single most important concept, upon which a Muslim's entire religious adherence rests. It unequivocally holds that God is indivisibly one (ahad) and single (wahid).
Meditations on First Philosophy, in which the existence of God and the immortality of the soul are demonstrated, often called simply the Meditations, is a philosophical treatise by René Descartes first published in Latin in 1641. The French translation was published in 1647 as Méditations Métaphysiques. The title may contain a misreading by the printer, mistaking animae immortalitas for animae immaterialitas, as suspected by A. Baillet.
Authenticity is a concept of personality in the fields of psychology, existential psychotherapy, existentialist philosophy, and aesthetics. In existentialism, authenticity is the degree to which a person's actions are congruent with their values and desires, despite external pressures to social conformity. The conscious self comes to terms with the condition of Geworfenheit, of having been thrown into an absurd world not of their own making, thereby encountering external forces and influences different from and other than the Self. A person’s lack of authenticity is considered bad faith in dealing with other people and with one's self; thus, authenticity is in the instruction of the Oracle of Delphi: “Know thyself.” Concerning authenticity in art, the philosophers Jean Paul Sartre and Theodor Adorno held opposing views and opinions about jazz, a genre of American music; Sartre said that jazz is authentic and Adorno said that jazz is inauthentic. Many musical subcultures require artistic authenticity, lest the community consider an artist to be a poseur for lacking authenticity ; artistic authenticity is integral to many genres of music, including but not limited to genres of rock, club music, and hip-hop.
Truthmaker theory is "the branch of metaphysics that explores the relationships between what is true and what exists". The basic intuition behind truthmaker theory is that truth depends on being. For example, a perceptual experience of a green tree may be said to be true because there actually is a green tree. But if there were no tree there, it would be false. So the experience by itself does not ensure its truth or falsehood, it depends on something else. Expressed more generally, truthmaker theory is the thesis that "the truth of truthbearers depends on the existence of truthmakers". A perceptual experience is the truthbearer in the example above. Various representational entities, like beliefs, thoughts or assertions can act as truthbearers. Truthmaker theorists are divided about what type of entity plays the role of truthmaker; popular candidates include states of affairs and tropes.
The existence of God is a subject of debate in the philosophy of religion and theology. A wide variety of arguments for and against the existence of God can be categorized as logical, empirical, metaphysical, subjective, or scientific. In philosophical terms, the question of the existence of God involves the disciplines of epistemology and ontology and the theory of value.
Vishishtadvaita is a school of Hindu philosophy belonging to the Vedanta tradition. Vedanta refers to the profound interpretation of the Vedas based on Prasthanatrayi. Vishishta Advaita, meaning "non-duality with distinctions", is a non-dualistic philosophy that recognizes Brahman as the supreme reality while also acknowledging its multiplicity. This philosophy can be characterized as a form of qualified monism, attributive monism, or qualified non-dualism. It upholds the belief that all diversity ultimately stems from a fundamental underlying unity.
The Cartesian circle is an example of fallacious circular reasoning attributed to French philosopher René Descartes. He argued that the existence of God is proven by reliable perception, which is itself guaranteed by God.

Christian existential apologetics differs from traditional approaches to Christian apologetics by basing arguments for Christian theism on the satisfaction of existential needs rather than on strictly logical or evidential arguments. Christian existential apologetics may also be distinguished from Christian existentialism and from experiential apologetics. The former is a philosophic outlook concerned with the human condition in general; the latter consists of evidential argumentation based on religious experience.
Romantic epistemology emerged from the Romantic challenge to both the static, materialist views of the Enlightenment (Hobbes) and the contrary idealist stream (Hume) when it came to studying life. Romanticism needed to develop a new theory of knowledge that went beyond the method of inertial science, derived from the study of inert nature, to encompass vital nature. Samuel Taylor Coleridge was at the core of the development of the new approach, both in terms of art and the 'science of knowledge' itself (epistemology). Coleridge's ideas regarding the philosophy of science involved Romantic science in general, but Romantic medicine in particular, as it was essentially a philosophy of the science(s) of life.
