10 Arguments of Aenesidemus and Agrippa

[Amun]

1) "The same impressions are not produced by the same objects owing to the differences in animals."

2) The same impressions are not produced by the same objects owing to the differences among human beings.

3) The same impressions are not produced by the same objects owing to the differences among the senses.

4) Owing to the "circumstances, conditions or dispositions," the same objects appear different. The same temperature, as established by instrument, feels very different after an extended period of cold winter weather (it feels warm) than after mild weather in the autumn (it feels cold). Time appears slow when young and fast as aging proceeds. Honey tastes sweet to most but bitter to someone with jaundice. A person with influenza will feel cold and shiver even though she is hot with a fever.

5) "Based on positions, distances, and locations; for owing to each of these the same objects appear different." The same tower appears rectangular at close distance and round from far away. The moon looks like a perfect sphere to the human eye, yet cratered from the view of a telescope.

6) “We deduce that since no object strikes us entirely by itself, but along with something else, it may perhaps be possible to say what the mixture compounded out of the external object and the thing perceived with it is like, but we would not be able to say what the external object is like by itself."

7) "Based, as we said, on the quantity and constitution of the underlying objects, meaning generally by "constitution" the manner of composition." So, for example, goat horn appears black when intact and appears white when ground up. Snow appears white when frozen and translucent as a liquid.

8) "Since all things appear relative, we will suspend judgement about what things exist absolutely and really existent. Do things which exist "differentially" as opposed to those things that have a distinct existence of their own, differ from relative things or not? If they do not differ, then they too are relative; but if they differ, then, since everything which differs is relative to something..., things which exist absolutely are relative."

9) "Based on constancy or rarity of occurrence." The sun is more amazing than a comet, but because we see and feel the warmth of the sun daily and the comet rarely, the latter commands our attention.

10) "There is a Tenth Mode, which is mainly concerned with Ethics, being based on rules of conduct, habits, laws, legendary beliefs, and dogmatic conceptions."
