To these I have lately added
two very _general           of _doubt_; The first was, that while I was
_awake_, I could not believe my self to perceive any thing, which I could
not think my self sometimes to perceive, tho I were _a sleep_; And seeing
I cannot believe, that what I seem to perceive in my _sleep_ proceeds
from _outward Objects_, what greater Reason have I to think so of what I
perceive whilst I am _awake_?
