Purley, make up the general theory of language,
which consists of the symbols of ideas represented by vocal
or written words; or by parts of those words, as their
terminations; or by their disposition in respect to their
order or succession; as further explained in Additional Note

"The GIANT FORM on Nature's centre stands,
And waves in ether his unnumber'd hands;
Whirls the bright planets in their silver spheres,
And the vast sun round other systems steers;
Till the last trump amid the thunder's roar
Sound the dread Sentence "TIME SHALL BE NO MORE!"

"Last steps Abbreviation, bold and strong, 391
And leads the volant trains of words along;
With sweet loquacity to HERMES springs,
And decks his forehead and his feet with wings.

VII. "As the soft lips and pliant tongue are taught
With other minds to interchange the thought;
And sound, the symbol of the sense, explains
In parted links the long ideal trains;
From clear conceptions of external things
The facile power of Recollection springs. 400

[Footnote: _In parted links_, l. 398. As our ideas consist of
successive trains of the motions, or changes of figure, of
the extremities of the nerves of one or more of our senses,
as of the optic or auditory nerves; these successive trains
of motion, or configuration, are in common life divided into
many links, to each of which a word or name is given, and it
is called an idea. This chain of ideas may be broken into
more or fewer links, or divided in different parts of it, by
the customs of different people. Whence the meanings of the
words of one language cannot always be exactly expressed by
those of another; and hence the acquirement of different
languages in their infancy may affect the modes of thinking
and reasoning of whole nations, or of different classes of
society; as the words of them do not accurately suggest the
same ideas, or parts of ideal trains; a circumstance which
has not been sufficiently analysed.]

"Whence REASON'S empire o'er the world presides,
And man from brute, and man from man divides;
Compares and measures by imagined lines
Ellipses, circles, tangents, angles, sines;
Repeats with nice libration, and decrees
