From all this it may be infered, that no other faculty is required, beside the senses, to convince us of the external existence of body.

But to prevent this inference, we need only weigh the three following considerations.

First, That, properly speaking, it is not our body we perceive, when we regard our limbs and members, but certain impressions, which enter by the senses; so that the ascribing a real and corporeal existence to these impressions, or to their objects, is an act of the mind as difficult to explain, as that which we examine at present.

Secondly, Sounds, and tastes, and smelts, though commonly regarded by the mind as continued independent qualities, appear not to have any existence in extension, and consequently cannot appear to the senses as situated externally to the body.

The reason, why we ascribe a place to them, shall be: considered afterwards.
