Knowledge, Conviction, and Belief
“ For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.”
Paul’s letter to the Romans 8:38–39 (NIV)
How did Paul know that? Why was he so convinced?
According to psychology and neuroscience, he didn’t know it, he was convinced of it. The difference reflects Cartesian dualism: the belief that we can know things about the natural world through scientific inquiry, but in the supernatural world, truth is a matter of conviction.
Academics draw distinctions between these and other terms, but in actual experience, the essence seems to be emotional content. Scientific knowledge is thought to be emotionally detached — it wears a lab coat, pours over data, expresses conclusions intellectually. It believes its conclusions, but questioning them is hardwired into scientific inquiry; science therefore must hold its truth in an open hand — all of which establish a reliable sense of what is “real.” Conviction, on the other hand, comes with heart, with a compelling sense of certainty. The emotional strength of conviction makes questioning its truth — especially religious convictions — something to be discouraged or punished.
Further, while knowledge may come with a Eureka! moment — that satisfying flash of suddenly seeing clearly — conviction often comes with a sense of being overtaken by an authority greater than ourselves — of being apprehended and humbled, left frightened and grateful for a second chance.
mid-15c., “the proving or finding of guilt of an offense charged,” from Late Latin convictionem(nominative convictio) “proof, refutation,” noun of action from past-participle stem of convincere “to overcome decisively,” from com-, here probably an intensive prefix (see com-), + vincere “to conquer” (from nasalized form of PIE root *weik- (3) “to fight, conquer”).
Meaning “mental state of being convinced or fully persuaded” is from 1690s; that of “firm belief, a belief held as proven” is from 1841. In a religious sense, “state of being convinced one has acted in opposition to conscience, admonition of the conscience,” from 1670s.
1520s, “to overcome in argument,” from Latin convincere “to overcome decisively,” from assimilated form of com-, here probably an intensive prefix (see com-), + vincere “to conquer” (from nasalized form of PIE root *weik- (3) “to fight, conquer”). Meaning “to firmly persuade or satisfy by argument or evidence” is from c. 1600. Related: Convinced; convincing; convincingly.
To convince a person is to satisfy his understanding as to the truth of a certain statement; to persuade him is, by derivation, to affect his will by motives; but it has long been used also for convince, as in Luke xx. 6, “they be persuaded that John was a prophet.” There is a marked tendency now to confine persuade to its own distinctive meaning. [Century Dictionary, 1897]
Both knowledge and conviction, and the needs they serve, are evolutionary survival skills: we need what they give us to be safe, individually and collectively. Knowledge satisfies our need to be rational, to think clearly and logically, to distinguish this from that, to put things into dependable categories. Conviction satisfies the need to be moved, and also to be justified — to feel as though you are in good standing in the cosmology of how life is organized.
Culturally, conviction is often the source of embarrassment, guilt, and shame, all of which have a key social function — they are part of the glue that holds society together. Becoming aware that we have transgressed societal laws or behavioral norms (the “conviction of sin”) often brings not just chastisement but also remorse and relief — to ourselves and to others in our community: we’ve been arrested, apprehended, overtaken by a corrective authority, and saved from doing further harm to ourselves and others.
Knowledge and conviction also have something else in common: both originate in the brain’s complex tangle of neural networks:
“It is unlikely that beliefs as wide-ranging as justice, religion, prejudice or politics are simply waiting to be found in the brain as discrete networks of neurons, each encoding for something different. ‘There’s probably a whole combination of things that go together,’ says [Peter Halligan, a psychologist at Cardiff University].
“And depending on the level of significance of a belief, there could be several networks at play. Someone with strong religious beliefs, for example, might find that they are more emotionally drawn into certain discussions because they have a large number of neural networks feeding into that belief.”
Where Belief Is Born, The Guardian (June 30,2005).
And thus protected by the knowledge and convictions wired into our neural pathways, we make our way through this precarious thing called “life.”
