Shorter 10 modes of skepticism

Modes of Skepticism are supposed to force you to suspend judgement because you cannot know or cannot be certain.

These are variations on Pyrrhonism:

  1. based on the variety in animals;
  2. on the differences in human beings;
  3. on the different structures of the organs of sense;
  4. on the circumstantial conditions;
  5. on positions and intervals and locations;
  6. on intermixtures;
  7. on the quantities and formations of the underlying objects;
  8. on the fact of relativity;
  9. on the frequency or rarity of occurrence;
  10. on the disciplines and customs and laws, the legendary beliefs and the dogmatic convictions.

These are fromĀ Aenesidemus:

  1. The feelings and perceptions of all living beings differ.
  2. People have physical and mental differences, which make things appear different to them.
  3. The different senses give different impressions of things.
  4. Our perceptions depend on our physical and intellectual conditions at the time of perception.
  5. Things appear different in different positions, and at different distances.
  6. Perception is never direct, but always through a medium. For example, we see things through the air.
  7. Things appear different according to variations in their quantity, color, motion, and temperature.
  8. A thing impresses us differently when it is familiar and when it is unfamiliar.
  9. All supposed knowledge is predication. All predicates give us only the relation of things to other things or to ourselves; they never tell us what the thing in itself is.
  10. The opinions and customs of people are different in different countries.
