      §21. He that will suffer himself, to be informed by Observation
and Experience, and not make his own Hypothesis the Rule of
Nature, will find few Signs of a Soul accustomed to much thinking
in a new born Child, and much fewer of any Reasoning at all. And
yet it is hard to imagine, that the rational Soul should think so much,
and not reason at all. And he that will consider, that Infants, newly
come into the World, spend the greatest part of their time in Sleep,
and are seldom awake, but when either Hunger calls for the Teat, or
some Pain, (the most importunate of all Sensations) or some other
violent Impression on the Body, forces the mind to perceive, and

attend to it. He, I say, who considers this, will, perhaps, find
Reason to imagine, That a Foetus in the Mothers Womb, differs not
much from the State of a Vegetable; but passes the greatest part of its
time without Perception or Thought, doing very little, but sleep
in a Place, where it needs not seek for Food, and is surrounded with
Liquor, always equally soft, and near of the same Temper; where
the Eyes have no Light, and the Ears, so shut up, are not very
susceptible of Sounds; and where there is little or no variety, or
change of Objects, to move the Senses.
