In predicate logic , an existentialquantification is the predication ref The term predication in grammar means the predicate of a sentence which refers to subject and is an adverb or adjective, or equivalent, that describes an attribute of the subject.

A counting quantifier is a Mathematics mathematical term for a quantifier of the form there exists at least k elements that satisfy property X . In first order logic with equality, counting quantifiers can be defined in terms of ordinary quantifiers, so in this context they are a notational shorthand. However, they are interesting in the context of logics such as two variable logic with counting that restrict the number of variables in formulas. Also, generalized counting quantifiers that say there exists infinitely many are not expressible using a finite number of formulas in first order logic.

Uncertainty quantification UQ is the science of quantitative characterization and reduction of Uncertainty uncertainties in applications. It tries to determine how likely certain outcomes are if some aspects of the system are not exactly known. An example would be to predict the acceleration of a human body in a head on crash with another car even if we exactly knew the speed, small differences in the manufacturing of individual cars, how tightly every bolt has been tightened, etc., will lead to different results that can only be predicted in a statistical sense. Many problems in the natural sciences and engineering are also rife with sources of uncertainty. computer model Computer simulation modeling is the most commonly used approach to study problems in uncertainty quantification UQ . Reasons for uncertainties Uncertainty can enter numerical or mathematical models in various contexts. For example The model structure, i.e., how accurately a mathematical model describes the true system for a real life situation, may only be known approximately. Models are almost always only approximations to reality. For example, the Maxwell equations describe electromagnetic fields very well yet, it is known that quantum electrodynamics is the correct description if field strengths become large. The numerical approximation, i.e., how appropriately a numerical method is used in approximating the operation of the system. Most models are too complicated to solve exactly. For example the finite element method may be used to approximate the solution of a partial differential equation , but this introduces an error the difference between the exact and the numerical solution .

Unreferenced date December 2009 Existential phenomenology is a philosophy philosophical current inspired by Martin Heidegger s 1927 work Sein und Zeit Being and Time and influenced by the existential work of S ren Kierkegaard and the phenomenological work of Edmund Husserl . In contrast with his former mentor Husserl, Heidegger put ontology before epistemology and thought that Phenomenology philosophy phenomenology would have to be based on an observation and analysis of Dasein being there , human being, investigating the fundamental ontology of the Lebenswelt Lifeworld Husserl s term underlying all so called regional ontologies of the special sciences. In contrast with the philosopher Kierkegaard, Heidegger wanted to explore the problem of Dasein existentially existenzial , rather than existentiell y existenziell because Heidegger argued Kierkegaard had already described the latter with penetrating fashion . Citation needed date September 2010 Development of existential phenomenology Besides Heidegger, other existential phenomenologists were Hannah Arendt , Emmanuel Levinas , Gabriel Marcel , Jean Paul Sartre , Maurice Merleau Ponty , and Samuel Todes .

Multiple issues COI January 2011 primary sources January 2011 notability January 2011 Existential counselling is a Philosophy philosophical form of counselling which addresses the situation of a person s life and situates the person firmly within the predictable challenges of the human condition. Existential counselling considers human living to take place within four dimensions physical, social, psychological and spiritual. It shows each of these dimensions to be constituted like a force field, within which predictable paradoxes, tensions and dilemmas play out. Human beings can learn to deal with these tensions and conflicts more effectively by facing up to the negatives as well as the positives of their lives, including the tensions of life and death, love and hate, strength and weakness and meaning and absurdity. Best known authors on existential counselling are Irvin Yalom in the USA through his book Existential Psychotherapy 1981 New York Basic Books and Emmy van Deurzen , who created the British School and who published her book Existential Counselling and Psychotherapy in 1988 London Sage Publications second edition 2002, third edition 2011 .

Expert subject Philosophy Logic date September 2009 No footnotes date November 2010 The existential fallacy , or existential instantiation , is a logical fallacy in Boolean logic while it is not in Aristotelian logic . In an existential fallacy, we presuppose that a class has members even when we are not explicitly told so that is, we assume that the class has existential import . An existential fallacy committed in a categorical syllogism is validity invalid because it has two universal premises and a particular conclusion. In other words, for the conclusion to be true, at least one member of the class must exist, but the premises do not establish this. Boolean logic In modern times, presupposition that a class has members is seen as unacceptable. In 1905, Bertrand Russell wrote an essay entitled The Existential Import of Proposition , in which he called this Boolean approach Guiseppe Peano Peano s interpretation . The fallacy does not occur in enthymeme s, where hidden premises required to make the syllogism valid assume the existence of at least one member of the class. Examples First example Let S subject and P predicate. Consider the following two propositions A proposition says, All S is P. I proposition says, Some S is P. This is an existential fallacy of subalternation . However, in Aristotelian logic, this mode of reasoning is perfectly permissible. Let S soldiers and P heroes. We then have All S soldiers are P heroes . Some S is P. That is, if all soldiers are heroes, then at least one of them must be a hero. Nevertheless, Boole came around with his objection. He said ...

Humanism Existential humanism is a concept that can be understood in several different ways. Sartre said Existentialism is a humanism because it expresses the power of human beings to make freely willed choices, independent of the influence of religion or society. Kierkegaard suggested that the best use of our capacity for making choices is to freely choose to live a fully human life that incorporates traditional human structures such as marriage. Camus , in his book The Plague , suggests that some of us may choose to be heroic, even knowing that it will bring us neither reward nor salvation, and Simone de Beauvoir , in her book The Ethics of Ambiguity , argues that embracing our own personal freedom requires us to fight for the freedoms of all humanity.

Existential clauses are clauses that indicate only an existence. In English, they are formed with the dummy subject construction also known as Syntactic expletive expletive with there , e.g. There are boys in the yard . Many languages do not require a dummy subject, e.g. Finnish language Finnish , where the sentence Pihalla on poikia is literally On the yard is boys . Some languages have a different verb for this purpose, e.g. Swedish language Swedish finnas , as in, Det finns pojkar p g rden , which is literally It is found boys on the yard or, more accurately, It exists boys on the yard . On the other hand, some languages do not require a Copula linguistics copula at all, and sentences analogous to In the yard boys are used. Possession or being under influence of something may also be indicated by existential clauses, e.g. Irish T ocras orm There is hunger on me , or Hungarian Van egy halam I have a fish literally Is a fish my , or also Hungarian Anna sz p Anna is beautiful literally Anna beautiful .
