Which detail best supports the idea that slaves are no better than animals?

i have no accurate knowledge of my age, never having seen any authentic record containing it.

by far the larger part of the slaves know as little of their ages as horses know of theirs, and it is the wish of most masters within my knowledge to keep their slaves thus ignorant.

my mother and i were separated when i was but an infant—before i knew her as my mother. it is a common custom, in the part of maryland from which i ran away, to part children from their mothers at a very early age.

the children unable to work in the field had neither shoes, stockings, jackets, nor trousers, given to them; their clothing consisted of two coarse linen shirts per year.
