nd, in his Fob. As I have
naturally an Aversion to much Speaking, and do not love to be the
Messenger of ill News, especially when it comes too late to be useful, I
left him to be convinced of his Mistake in due time, and continued my
Walk, reflecting on these little Absences and Distractions in Mankind,
and resolving to make them the Subject of a future Speculation.

I was the more confirmed in my Design, when I considered that they were
very often Blemishes in the Characters of Men of excellent Sense; and
helped to keep up the Reputation of that Latin Proverb, [1] which Mr.
_Dryden_ has Translated in the following Lines:

_Great Wit to Madness sure is near ally'd,
And thin Partitions do their Bounds divide._

My Reader does, I hope, perceive, that I distinguish a Man who is
_Absent_, because he thinks of something else, from one who is _Absent_,
because he thinks of nothing at all: The latter is too innocent a
Creature to be taken notice of; but the Distractions of the former may,
I believe, be generally accounted for from one of these Reasons.

Either their Minds are wholly fixed on some particular Science, which is
often the Case of Mathematicians and other learned Men; or are wholly
taken up with some Violent Passion, such as Anger, Fear, or Love, which
ties the Mind to some distant Object; or, lastly, these Distractions
proceed from a certain Vivacity and Fickleness in a Man's Temper, which
while it raises up infinite Numbers of _Ideas_ in the Mind, is
continually pushing it on, without allowing it to rest on any particular
Image. Nothing therefore is more unnatural than the Thoughts and
Conceptions of such a Man, which are seldom occasioned either by the
Company he is in, or any of those Objects which are placed before him.
While you fancy he is admiring a beautiful Woman, 'tis an even Wager
that he is solving a Proposition in _Euclid_; and while you may imagine
he is reading the _Paris_ Gazette, it is far from being impossible, that
he is pulling down and rebuilding the Front of his Country-house.

At the same time that I am endeavouring to expose this Weakness in
others, I shall readily confess that I once laboured under the same
Infirmity myself. The Method I took to conquer it was a firm Resolution
to learn something from whatever I was obliged to see or hear. There is
a way of Thinking if a Man can attain to it, by which he may strike
somewhat out of any thing. I can at present observe those Star
