Doubt You Cannot Manufacture
Descartes told philosophy to begin by doubting everything and to end with whatever the individual mind finds clear. Peirce answers that a doubt has to be real before it can do any work, and that the lone mind is the wrong court to settle anything in.
Four Cartesian instructions are answered one at a time, and the replacement image carries the case: not a chain, no stronger than its weakest link, but a cable of slender fibres closely wound. Certainty is nowhere available and turns out not to be needed, because inquiry is something a community does and agreement among candid investigators is the only mark a science has. One gives up a prejudice when something forces it, not on command.

- You say doubting everything at the start is as useless as going to the North Pole to reach Constantinople. What goes wrong when someone pretends to doubt?
- Real doubt only arrives when something forces it. Doesn't that leave a comfortable person with no reason ever to inquire?
- Someone wants to examine their beliefs honestly but finds they cannot make themselves doubt what they still believe. What should they do instead?
- Reasoning should be a cable of many slender fibres, not a chain, you say. Does that mean no single argument can ever settle anything?
