I say, a new set of perceptions: For we may well suppose in general, but it is impossible for us distinctly to conceive, objects to be in their nature any thing but exactly the same with perceptions.

What then can we look for from this confusion of groundless and extraordinary opinions but error and falshood?
And how can we justify to ourselves any belief we repose in them?
This sceptical doubt, both with respect to reason and the senses, is a malady, which can never be radically cured, but must return upon us every moment, however we may chace it away, and sometimes may seem entirely free from it.

It is impossible upon any system to defend either our understanding or senses; and we but expose them farther when we endeavour to justify them in that manner.

As the sceptical doubt arises naturally from a profound and intense reflection on those subjects, it always encreases, the farther we carry our reflections, whether in opposition or conformity to it.

Carelessness and in-attention alone can afford us any remedy.
