- IDEA 1 OF 8
Pragmatism tests ideas by consequences
James presents pragmatism as a method for settling philosophical disputes by asking what practical difference each view makes.
If two theories lead to no different consequences in experience, he argues, the dispute between them is empty.
- IDEA 2 OF 8
A squirrel shows the method
James describes a camping argument about whether a man running around a tree goes around a squirrel that keeps moving to stay on the other side.
He shows the answer depends on what we mean by going around, so the disagreement dissolves.
- IDEA 3 OF 8
Ideas have a cash value
James asks what the cash value of an idea is: how it would change our experience and actions.
Ideas that make no practical difference, he suggests, may be meaningless. Practice gives ideas meaning.
- IDEA 4 OF 8
Two temperaments shape philosophy
James distinguishes tender-minded people, who prefer principles and religion, from tough-minded people, who prefer facts and science.
He presents pragmatism as a bridge between them. It serves both temperaments. Both can agree.
- IDEA 5 OF 8
Truth is what works
James argues that true ideas are those we can assimilate, validate and verify.
Truth is not a fixed copy of reality but something that happens to ideas as they prove useful.
- IDEA 6 OF 8
Theories are tools
James describes pragmatism as a corridor that opens onto many rooms, each a different theory.
Pragmatism does not take sides but helps people move between theories and test them. It is a method.
- IDEA 7 OF 8
Truth can change
James suggests that truth grows as experience grows.
Ideas that once worked may be replaced by better ones. Knowledge is never finished, and new experience can always revise what we believe.
- IDEA 8 OF 8
Philosophy should serve life
James argues that philosophy should help people live better, not just debate abstract questions.
Pragmatism, he believes, makes philosophy practical. Ideas should help people act and live more wisely. Use matters.
