Meaning of life

Scientific inquiry and perspectives

Where Do We Come From? What Are We? Where Are We Going?, one of Post-Impressionist Paul Gauguin’s most famous paintings

The meaning of life, or the answer to the question: "What is the meaning of life?", pertains to the significance of living or existence in general. Many other related questions include: "Why are we here?", "What is life all about?", or "What is the purpose of existence?" There have been a large number of proposed answers to these questions from many different cultural and ideological backgrounds. The search for life's meaning has produced much philosophicalscientifictheological, and metaphysical speculation throughout history. Different people and cultures believe different things for the answer to this question.

The meaning of life as we perceive it is derived from philosophical and religious contemplation of, and scientific inquiries about existencesocial tiesconsciousness, and happiness. Many other issues are also involved, such as symbolic meaningontologyvaluepurposeethicsgood and evilfree will, the existence of one or multiple godsconceptions of God, the soul, and the afterlife. Scientific contributions focus primarily on describing related empirical facts about the universe, exploring the context and parameters concerning the "how" of life. Science also studies and can provide recommendations for the pursuit of well-being and a related conception of morality. An alternative, humanistic approach poses the question, "What is the meaning of my life?"

Questions about the meaning of life have been expressed in a broad variety of ways, including the following:

  • What is the meaning of life? What’s it all about? Who are we?
  • Why are we here? What are we here for?
  • What is the origin of life?
  • What is the nature of life? What is the nature of reality?
  • What is the purpose of life? What is the purpose of one’s life?
  • What is the significance of life? – see also § Psychological significance and value in life
  • What is meaningful and valuable in life?
  • What is the value of life?
  • What is the reason to live? What are we living for?

These questions have resulted in a wide range of competing answers and arguments, from scientific theories, to philosophical, theological, and spiritual explanations.

Scientific inquiry and perspectives:

Many members of the scientific community and philosophy of science communities think that science can provide the relevant context, and set of parameters necessary for dealing with topics related to the meaning of life. In their view, science can offer a wide range of insights on topics ranging from the science of happiness to death anxiety. Scientific inquiry facilitates this through nomological investigation into various aspects of life and reality, such as the Big Bangthe origin of life, and evolution, and by studying the objective factors which correlate with the subjective experience of meaning and happiness.

Psychological significance and value in life

Researchers in positive psychology study empirical factors that lead to life satisfaction, full engagement in activities,making a fuller contribution by utilizing one’s personal strengths,and meaning based on investing in something larger than the self. Large-data studies of flow experiences have consistently suggested that humans experience meaning and fulfillment when mastering challenging tasks, and that the experience comes from the way tasks are approached and performed rather than the particular choice of task. For example, flow experiences can be obtained by prisoners in concentration camps with minimal facilities, and occur only slightly more often in billionaires. A classic example is of two workers on an apparently boring production line in a factory. One treats the work as a tedious chore while the other turns it into a game to see how fast she can make each unit, and achieves flow in the process.

Neuroscience describes rewardpleasure, and motivation in terms of neurotransmitter activity, especially in the limbic system and the ventral tegmental area in particular. If one believes that the meaning of life is to maximize pleasure and to ease general life, then this allows normative predictions about how to act to achieve this. Likewise, some ethical naturalists advocate a science of morality—the empirical pursuit of flourishing for all conscious creatures.

Experimental philosophy and neuroethics research collects data about human ethical decisions in controlled scenarios such as trolley problems. It has shown that many types of ethical judgment are universal across cultures, suggesting that they may be innate, whilst others are culture specific. The findings show actual human ethical reasoning to be at odds with most logical philosophical theories, for example consistently showing distinctions between action by cause and action by omission which would be absent from utility based theories. Cognitive science has theorized about differences between conservative and liberal ethics and how they may be based on different metaphors from family life such as strong fathers vs nurturing mother models.

Neurotheology is a controversial field which tries to find neural correlates and mechanisms of religious experience. Some researchers have suggested that the human brain has innate mechanisms for such experiences and that living without using them for their evolved purposes may be a cause of imbalance. Studies have reported conflicted results on correlating happiness with religious belief and it is difficult to find unbiased meta-analyses.[citation needed]

Sociology examines value at a social level using theoretical constructs such as value theory, norms, anomie, etc. One value system suggested by social psychologists, broadly called Terror Management Theory, states that human meaning is derived from a fundamental fear of death, and values are selected when they allow us to escape the mental reminder of death.

Alongside this, there are a number of theories about the way in which humans evaluate the positive and negative aspects of their existence and thus the value and meaning they place on their lives. For example, depressive realism posits an exaggerated positivity in all except those experiencing depressive disorders who see life as it truly is, and David Benatar theorises that more weight is generally given to positive experiences, providing bias towards an over-optimistic view of life.

Emerging research shows that meaning in life predicts better physical health outcomes. Greater meaning has been associated with a reduced risk of Alzheimer’s disease,reduced risk of heart attack among individuals with coronary heart disease, reduced risk of stroke, and increased longevity in both American and Japanese samples.In 2014, the British National Health Service began recommending a five step plan for mental well-being based on meaningful lives, whose steps are: (1) Connect with community and family; (2) Physical exercise; (3) Lifelong learning; (4) Giving to others; (5) Mindfulness of the world around you.

Origin and nature of biological life

DNA, the molecule containing the genetic instructions for the development and functioning of all known living organisms.

The exact mechanisms of abiogenesis are unknown: notable hypotheses include the RNA world hypothesis (RNA-based replicators) and the iron-sulfur world hypothesis (metabolism without genetics). The process by which different lifeforms have developed throughout history via genetic mutation and natural selection is explained by evolution. At the end of the 20th century, based upon insight gleaned from the gene-centered view of evolution, biologists George C. WilliamsRichard Dawkins, and David Haig, among others, concluded that if there is a primary function to life, it is the replication of DNA and the survival of one’s genes.This view has not achieved universal agreement; Jeremy Griffith is a notable exception, maintaining that the meaning of life is to be integrative. Responding to an interview question from Richard Dawkins about "what it is all for", James Watson stated "I don’t think we’re for anything. We’re just the products of evolution."

Though scientists have intensively studied life on Earth, defining life in unequivocal terms is still a challenge. Physically, one may say that life "feeds on negative entropy" which refers to the process by which living entities decrease their internal entropy at the expense of some form of energy taken in from the environment. Biologists generally agree that lifeforms are self-organizing systems which regulate their internal environments as to maintain this organized statemetabolism serves to provide energy, and reproduction causes life to continue over a span of multiple generations. Typically, organisms are responsive to stimuli and genetic information changes from generation to generation, resulting in adaptation through evolution; this optimizes the chances of survival for the individual organism and its descendants respectively.

Non-cellular replicating agents, notably viruses, are generally not considered to be organisms because they are incapable of independent reproduction or metabolism. This classification is problematic, though, since some parasites and endosymbionts are also incapable of independent life. Astrobiology studies the possibility of different forms of life on other worlds, including replicating structures made from materials other than DNA.

Origins and ultimate fate of the universe

Though the Big Bang theory was met with much skepticism when first introduced, it has become well-supported by several independent observations. However, current physics can only describe the early universe from 10−43 seconds after the Big Bang (where zero time corresponds to infinite temperature); a theory of quantum gravity would be required to understand events before that time. Nevertheless, many physicists have speculated about what would have preceded this limit, and how the universe came into being. For example, one interpretation is that the Big Bang occurred coincidentally, and when considering the anthropic principle, it is sometimes interpreted as implying the existence of a multiverse.

The ultimate fate of the universe, and implicitly humanity, is hypothesized as one in which biological life will eventually become unsustainable, such as through a Big FreezeBig Rip, or Big Crunch.

Theoretical cosmology studies many alternative speculative models for the origin and fate of the universe beyond the Big Bang theory. A recent trend has been models of the creation of 'baby universes' inside black holes, with our own Big Bang being a white hole on the inside of a black hole in another parent universe.Multiverse theories claim that every possibility of quantum mechanics is played out in parallel universes.

Scientific questions about the mind

The nature and origin of consciousness and the mind itself are also widely debated in science. The explanatory gap is generally equated with the hard problem of consciousness, and the question of free will is also considered to be of fundamental importance. These subjects are mostly addressed in the fields of cognitive science, neuroscience (e.g. the neuroscience of free will) and philosophy of mind, though some evolutionary biologists and theoretical physicists have also made several allusions to the subject.

Hieronymus Bosch’s Ascent of the Blessed depicts a tunnel of light and spiritual figures, often described in reports of near-death experiences.

Reductionistic and eliminative materialistic approaches, for example the Multiple Drafts Model, hold that consciousness can be wholly explained by neuroscience through the workings of the brain and its neurons, thus adhering to biological naturalism.[41][42][43]

On the other hand, some scientists, like Andrei Linde, have considered that consciousness, like spacetime, might have its own intrinsic degrees of freedom, and that one's perceptions may be as real as (or even more real than) material objects.[44] Hypotheses of consciousness and spacetime explain consciousness in describing a "space of conscious elements",[44] often encompassing a number of extra dimensions.[45] Electromagnetic theories of consciousness solve the binding problem of consciousness in saying that the electromagnetic field generated by the brain is the actual carrier of conscious experience; there is however disagreement about the implementations of such a theory relating to other workings of the mind.[46][47] Quantum mind theories use quantum theory in explaining certain properties of the mind. Explaining the process of free will through quantum phenomena is a popular alternative to determinism.

Parapsychology

Based on the premises of non-materialistic explanations of the mind, some have suggested the existence of a cosmic consciousness, asserting that consciousness is actually the "ground of all being".Proponents of this view cite accounts of paranormal phenomena, primarily extrasensory perceptions and psychic powers, as evidence for an incorporeal higher consciousness. In hopes of proving the existence of these phenomena, parapsychologists have orchestrated various experiments, but successful results might be due to poor experimental controls and might have alternative explanations.

Nature of meaning in life

The most common[quantify] definitions of meaning in life involve three components.[citation needed] First, Reker and Wong define personal meaning as the "cognizance of order, coherence and purpose in one’s existence, the pursuit and attainment of worthwhile goals, and an accompanying sense of fulfillment" . In 2016 Martela and Steger defined meaning as coherence, purpose, and significance. In contrast, Wong has proposed a four-component solution to the question of meaning in life, with the four components purpose, understanding, responsibility, and enjoyment (PURE):

  • You need to choose a worthy purpose or a significant life goal.
  • You need to have sufficient understanding of who you are, what life demands of you, and how you can play a significant role in life.
  • You and you alone are responsible for deciding what kind of life you want to live, and what constitutes a significant and worthwhile life goal.
  • You will enjoy a deep sense of significance and satisfaction only when you have exercised your responsibility for self-determination and actively pursue a worthy life-goal.

Thus, a sense of significance permeates every dimension of meaning, rather than stands as a separate factor.

Although most psychology researchers consider meaning in life as a subjective feeling or judgment, most philosophers (e.g., Thaddeus Metz, Daniel Haybron) propose that there are also objective, concrete criteria for what constitutes meaning in life. Wong has proposed that whether life is meaningful depends not only on subjective feelings but, more importantly, on whether a person’s goal-striving and life as a whole is meaningful according to some objective normative standard.
