Pragmatism holds that ideas are not representations of an external reality but instruments people develop to cope with their environment, much like forks or knives. Their value lies in what they enable us to do, not in how accurately they correspond to a fixed truth.
What we believe is produced by the groups and circumstances we belong to rather than by isolated individual reasoning, so thought is fundamentally a collective and contingent activity. This reframes truth as something arrived at through inquiry within a community rather than discovered alone.
Oliver Wendell Holmes Jr. emerged from the carnage of the Civil War distrusting certainty itself, having watched abstract moral convictions drive men to slaughter. This experience seeded a generation's suspicion of fixed ideologies and a preference for provisional, testable beliefs over absolute principles.
A belief is 'true' not because it matches a pre-existing reality but because it proves useful and survives the test of consequences and ongoing inquiry. Truth is therefore mutable, plural, and earned through experiment rather than fixed in advance.
