15 ideas
How can a belief exist if its object doesn't exist? [Plato]
     Full Idea: If the object of a belief is what is not, the object of this belief is nothing; but if there is no object to a belief, then that is not belief at all.
     From: Plato (Theaetetus [c.368 BCE], 189a)
We can't believe apparent falsehoods, or deny apparent truths [Epictetus]
     Full Idea: It is impossible to assent to an apparent falsehood, or to deny an apparent truth.
     From: Epictetus (The Discourses [c.56], 3.07.15)
     A reaction: The way some philosophers write you would think that most beliefs just result from private whims or social fashion. That happens, of course, but most beliefs result from direct contact with reality.
Belief is not an intellectual state or act, because propositions are affirmed or denied by the will [Descartes, by Zagzebski]
     Full Idea: Descartes claimed that belief is not purely an intellectual state or act, since it is not the intellect that affirms or denies a proposition proposed for its consideration, but the will.
     From: report of René Descartes (Meditations [1641], IV) by Linda Trinkaus Zagzebski - Virtues of the Mind 4.2
     A reaction: This is the canonical idea of 'doxastic voluntarism' - that we choose what to believe or not believe. In modern times this view has become deeply unfashionable. I don't we should wholly reject the possibility of choosing to believe something.
When two ideas agree in my mind, I cannot refuse to see and know it [Locke]
     Full Idea: When the agreement of any two ideas appears to our minds, I can no more refuse to perceive, no more avoid knowing it, than I can avoid seeing those objects which I turn my eyes to.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.20.16)
     A reaction: Note that he is not just saying that we cannot resist believing what becomes evident to us, but he actually asserts that we cannot avoid 'knowing' it. This seems to imply that knowledge may be more basic than belief (as Williamson and Hossack argue).
'Natural beliefs' are unavoidable, whatever our judgements [Hume, by Strawson,G]
     Full Idea: Hume has a doctrine of "natural belief", about the sorts of things we can't help believing, in 'common' or everyday life, irrespective of our philosophical conclusions.
     From: report of David Hume (Enquiry Conc Human Understanding [1748]) by Galen Strawson - The Secret Connexion App C
Beliefs are built up by resemblance, contiguity and causation [Hume]
     Full Idea: Belief, where it reaches beyond the memory or senses, arises from resemblance, contiguity or causation, with the same transition of thought and vivacity of conception.
     From: David Hume (Enquiry Conc Human Understanding [1748], V.II.44)
Belief is a feeling, independent of the will, which arises from uncontrolled and unknown causes [Hume]
     Full Idea: Belief consists merely in a certain feeling or sentiment; in something, that depends not on the will, but must arise from certain determinate causes and principles, of which we are not master.
     From: David Hume (Treatise of Human Nature, + Appendix [1740], Appen p.2)
     A reaction: This is the opposite of Descartes' 'doxastic voluntarism' (i.e. we choose what to believe). If you want to become a Christian, steep yourself in religious literature, and the company of religious people. It will probably work.
Belief is no more rational than is tasting and smelling [Hamann]
     Full Idea: Belief happens as little in terms of reasons as tasting and smelling.
     From: J.G. Hamann (works [1770], v2:74), quoted by Andrew Bowie - Introduction to German Philosophy
     A reaction: That is one idea definitively expressed! I take it as only a partial truth. Beliefs happen as a result of observation and experience. But someone can draw our attention to something (and we can hunt it out ourselves), which is giving a reason for belief.
We have an 'instinctive' belief in the external world, prior to all reflection [Russell]
     Full Idea: We find a belief in an independent external world ready in ourselves as soon as we begin to reflect: it is what may be called an 'instinctive' belief.
     From: Bertrand Russell (Problems of Philosophy [1912], Ch. 2)
     A reaction: Somewhere Hume calls this a 'natural belief', and it is fairly central to his idea that most of our beliefs are built up fairly mechanically by associations. I am tempted to ask whether such things even count as beliefs, if they are so uncritical.
I just confront the evidence, and let it act on me [Ramsey]
     Full Idea: I can but put the evidence before me, and let it act on my mind.
     From: Frank P. Ramsey (The Foundations of Mathematics [1925], p.202), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 70 'Deg'
     A reaction: Potter calls this observation 'downbeat', but I am an enthusiastic fan. It is roughly my view of both concept formation and of knowledge. You soak up the world, and respond appropriately. The trick is in the selection of evidence to confront.
Some beliefs are only inferred when needed, like 'Shakespeare had not telephone' [Fodor]
     Full Idea: Maybe some of your beliefs are inferred 'online' from what you have in your files, along with your inferential rules. 'Shakespeare didn't have a telephone' is a classic example, which we infer if the occasion arises.
     From: Jerry A. Fodor (LOT 2 [2008], Ch.3 App)
     A reaction: A highly persuasive example. There seem to be a huge swathe of blatantly obvious beliefs (especially negative ones) which may never cross our minds during an entire lifetime, but to which we certainly subscribe.
Beliefs are based on perception, memory, introspection or reason [Audi,R]
     Full Idea: The four basic kinds of belief are rooted in perception, memory, introspective consciousness, and reason.
     From: Robert Audi (Epistemology: contemporary introduction [1998], Intr.p.7)
Some beliefs are fairly voluntary, and others are not at all so [Zagzebski]
     Full Idea: My position is that beliefs, like acts, arrange themselves on a continuum of degrees of voluntariness, ranging from quite a bit to none at all.
     From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], I 4.2)
     A reaction: I'm sure we have no idea how we came to hold many of our beliefs, and if we see a cat, nothing seems to intervene between the seeing and the believing. But if you adopt a religion, believing its full creed is a big subsequent effort.
Causal theories of belief make all beliefs true, and can't explain belief about the future [Lowe]
     Full Idea: The causal theory of beliefs seems condemned to treat all beliefs as true, which is absurd, …and we do not want to say that tomorrow's rain 'causes' today's belief that it will rain tomorrow.
     From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4)
     A reaction: This is aimed at Fodor. A false belief might be caused by reality if one had one's internal wires crossed, and a belief about the future might be caused by events happening now. This theory is not dead.
'Evidentialists' say, and 'voluntarists' deny, that we only believe on the basis of evidence [Engel]
     Full Idea: The 'evidentialists' (such as Locke and Hume) deny, and the 'voluntarists' (such as William James) affirm, that we ought to, or at least may, believe for other reasons than evidential epistemic reasons (e.g. for pragmatic reasons).
     From: Pascal Engel (Truth [2002], §5.2)
     A reaction: No need to be black-or-white here. Blatant evidence compels belief, but we may also come to believe by spotting a coherence, without additional evidence. We can also be in a state of trying to believe something. But see 4764.
