Belief

Belief is the psychological state in which an individual is convinced of the truth of a proposition. Like the related concepts truth, knowledge, and wisdom, there is no precise definition of belief on which scholars agree, but rather numerous theories and continued debate about the nature of belief.

Belief, knowledge and epistemology

According an analysis dating back to Plato^[1], knowledge is justified true belief. False beliefs are not knowledge, even if the individual believes them to be true; a sincere believer in the flat earth theory does not know that the Earth is flat. Unknown facts are not knowledge, because they are not known by any individual; it is the belief element in justified-true-belief that makes the link between a state of affairs and an individual. Unjustified true beliefs are lucky guesses, and therefore not knowledge.

However, some people — not usually philosophers — use the word "belief" in a way that is opposed to knowledge. As far as they are concerned, something is either believed or known (or rejected entirely).

Belief as a psychological theory

Mainstream psychology and related disciplines have traditionally treated belief as if it were the simplest form of mental representation and therefore one of the building blocks of conscious thought. Philosophers have tended to be more rigorous in their analysis and much of the work examining the viability of the belief concept stems from philosophical analysis.

The concept of belief presumes a subject (the believer) and an object of belief (the proposition) so like other propositional attitudes, belief implies the existence of mental states and intentionality, both of which are hotly debated topics in the philosophy of mind and whose foundations and relation to brain states are still controversial.

Beliefs are sometimes divided into core beliefs (those which you may be actively thinking about) and dispositional beliefs (those which you may ascribe to but have never previously thought about). For example, if asked 'do you believe tigers wear pink pyjamas ?' a person might answer that they do not, despite the fact they may never have thought about this situation before. ^[2]

The idea that a belief is a mental state is much more contentious. While some philosophers have argued that beliefs are represented in the mind as sentence-like constructs others have gone as far as arguing that there is no consistent or coherent mental representation that underlies our common use of the belief concept and is therefore obsolete and should be rejected.

This has important implications for understanding the neuropsychology and neuroscience of belief. If the concept of belief is incoherent or ultimately indefensible then any attempt to find the underlying neural processes which support it will fail. If the concept of belief does turn out to be useful then this goal should (in principle) be achievable.

Philosopher Lynne Rudder Baker has outlined four main contemporary approaches to belief in her book Saving Belief:

• Our common-sense understanding of belief is correct - Sometimes called the ‘mental sentence theory’, in this conception, beliefs exist as coherent entities and the way we talk about them in everyday life is a valid basis for scientific endeavour. Jerry Fodor is one of the principal defenders of this point of view.
• Our common-sense understanding of belief may not be entirely correct, but it is close enough to make some useful predictions - This view argues that we will eventually reject the idea of belief as we use it now, but that there may be a correlation between what we take to be a belief when someone says 'I believe that snow is white' and however a future theory of psychology will explain this behaviour. Most notably philosopher Stephen Stich has argued for this particular understanding of belief.
• Our common-sense understanding of belief is entirely wrong and will be completely superseded by a radically different theory which will have no use for the concept of belief as we know it - Known as eliminativism, this view, (most notably proposed by Paul and Patricia Churchland), argues that the concept of belief is like obsolete theories of times past such as the four humours theory of medicine, or the phlogiston theory of combustion. In these cases science hasn’t provided us with a more detailed account of these theories, but completely rejected them as valid scientific concepts to be replaced by entirely different accounts. The Churchlands argue that our common-sense concept of belief is similar, in that as we discover more about neuroscience and the brain, the inevitable conclusion will be to reject the belief hypothesis in its entirety.
• Our common-sense understanding of belief is entirely wrong, however treating people, animals and even computers as if they had beliefs, is often a successful strategy - The major proponents of this view, Daniel Dennett and Lynne Rudder Baker, are both eliminativists in that they believe that beliefs are not a scientifically valid concept, but they don’t go as far as rejecting the concept of belief as a predictive device. Dennett gives the example of playing a computer at chess. While few people would agree that the computer held beliefs, treating the computer as if it did (e.g. that the computer believes that taking the opposition’s queen will give it a considerable advantage) is likely to be a successful and predictive strategy. In this understanding of belief, named by Dennett the intentional stance, belief based explanations of mind and behaviour are at a different level of explanation and are not reducible to those based on fundamental neuroscience although both may be explanatory at their own level.

Is belief voluntary?

Most philosophers hold the view that belief formation is to some extent spontaneous and involuntary.^{[citation needed]} Some people think that one can choose to investigate and research a matter but that one can not choose to believe. On the other hand, most people have the impression that in some cases people don't believe things because they don't want to believe, especially about a matter in which they are emotionally involved.

If one has an external inducement to belief, such as a prospective marriage partner, he may be unable to drastically change his true belief in order to obtain the desired reward. The best he might do would be to pretend at belief. There is a possibility that with study, he would come to change his belief, depending on his earlier sources and his confidence in the validity of new ones.

Delusional beliefs

Delusions are defined as beliefs in psychiatric diagnostic criteria (for example in the Diagnostic and Statistical Manual of Mental Disorders). Psychiatrist and historian G.E. Berrios has challenged the view that delusions are genuine beliefs and instead labels them as "empty speech acts", where affected persons are motivated to express false or bizarre belief statements due to an underlying psychological disturbance. However, the majority of mental health professionals and researchers treat delusions as if they were genuine beliefs.

Richard Dawkins, Sam Harris, and a number of other critics of religion have proposed the idea that many (if not most) faith-based religious beliefs are actually delusional beliefs. Some critics of atheism disagree with this view of religious beliefs. John P. Koster (The Atheist Syndrome), R.C. Sproul (If There is a God Why are There Atheists), Ravi Zacharias (The Real Face of Atheism), Alister McGrath (The Twilight of Atheism), and Paul Vitz (The Psychology of Atheism) have all argued the contrary to one degree or another.

In Lewis Carroll's Alice Through the Looking Glass, the White Queen says, "Why, sometimes I've believed as many as six impossible things before breakfast." This is often quoted in mockery of the common ability of people entertain beliefs contrary to fact.

Limiting beliefs

The term limiting belief is used for a belief that inhibits exploration of a wider cognitive space than would otherwise be the case. Examples of limiting beliefs are seen both in animals and people. These may be strongly held beliefs, or held unconsciously, and are often tied in with self-image or perceptions about the world. Everyday examples of limiting beliefs:

• That one has specific capabilities, roles, or traits which cannot be escaped or changed.
• That one cannot succeed so there is no point committing to trying.
• That a particular opinion is right therefore there is no point considering other viewpoints.
• That a particular action or result is the only way to resolve a problem.
