Mr. Pope has well observed, that—

“The proper study of mankind, is Man:”—

But, in order that he may be enabled to know himself, it is

indispensably necessary for him to acquire such a knowledge of other

created beings that surround him, as the limited nature of his faculties

will allow. He must attentively observe the operations of nature in the

material universe, survey with a reflecting mind its stupendous fabric,

and study its laws. Hence, he will be made acquainted, and although in a

partial, yet not an inconsiderable degree, with the powers and extent of

that intellectual principle which he finds in the government of the

moral, as well as the natural world. And being thus enabled to know his

own proper standing in creation, and his appropriate relation to all its

parts, he will by these means be qualified to ascend to those enquiries,

which will open to his mind a just sense of the attributes of the Deity,

of whose existence he will feel a perfect conviction. In this way, will

man obtain a due knowledge of his own “being, end and aim;” and become

fully sensible of his entire dependence on his Creator: while he will

thereby learn, that he incessantly owes him the highest adoration and

the most devoted service.[35] In this way it is, that the philosopher,

more especially the astronomer,—

“Looks, through Nature, up to Nature’s God.”[36]

_Pope’s Ess. on Man._

Footnote 35:

Man will, unquestionably, by taking an extensive range in the

contemplation of nature, proportionably enlarge his intuitive

conceptions of the attributes of her Almighty First Cause; of whose

transcendently exalted existence, the study of his own being, one of

nature’s greatest works, will have taught him the reality: and a due

knowledge of himself, alone, will also instruct him in the dependent

nature of his condition, and the duties resulting from that state of

dependence, in his humble relation to the Supreme being.

Mr. Smart, in the poem before quoted, has prettily expressed this

idea, in the following lines:—

“Vain were th’ attempt, and impious, to trace

Thro’ _all_ his works th’ Artificer Divine—

And tho’ no shining sun, nor twinkling star,

Bedeck’d the crimson curtains of the sky;

Tho’ neither vegetable, beast, nor bird,

Were extant on the surface of this ball,

Nor lurking gem beneath; tho’ the great sea

Slept in profound stagnation, and the air

Had left no thunder to pronounce its Maker;

Yet Man at home, _within himself_, might find

The Deity immense; and, in that frame

So fearfully, so wonderfully made,

See and adore his Providence and Pow’r.”

Footnote 36:

The same sentiment is beautifully expressed by Thomson, in the

following apostrophe:

“With thee, serene Philosophy! with thee,

And thy bright garland, let me crown my song!

Effusive source of evidence, and truth!

A lustre shedding o’er th’ ennobled mind,

Stronger than summer-noon; and pure as that,

Whose mild vibrations soothe the parted soul,

New to the dawning of celestial day.

Hence through her nourish’d pow’rs, enlarged by thee,

She springs aloft, with elevated pride,

Above the tangling mass of low desires,

That bind the fluttering crowd; and angel-wing’d,

The heights of science and of virtue gains,

Where all is calm and clear; with nature round,

Or in the starry regions, or th’ abyss,

To reason’s or to fancy’s eye display’d:

The _First_ up-tracing, from the dreary void,

The chain of causes and effects to Him,

The world producing essence, who alone

Possesses being; while the _Last_ receives

The whole magnificence of heaven and earth,

And every beauty, delicate or bold,

Obvious or more remote, with livelier sense,

Diffusive painted on the rapid mind.”

_Summer_, l. 1729 and seq.

Besides the various and important uses of astronomy, here pointed out,

it is connected, by means of numerous ramifications, with other

departments of science, directed to some of the most useful pursuits of

human life. Lalande has even shewn us, in the preface to his

_Astronomie_, in what manner this science has a relation to the

administration of civil and ecclesiastical affairs, to medicine, and to

agriculture. A knowledge of astronomy is obviously connected, by means

of chronology, with history. It is even a necessary study, in order to

become acquainted with the heathen mythology; and many beautiful

passages in the works of the ancient poets can neither be distinctly

understood nor properly relished, without a knowledge of the stars: nay,

that finely poetical one, in the book of Job, in which the Deity is

represented as manifesting to that patient man of affliction and sorrow

the extreme imbecility of his nature, is unintelligible without some

knowledge of astronomy:—

“Canst thou bind the sweet influences of Pleiades, or loose the bands of

Orion?—

Canst thou bring forth Mazzaroth in his season; or canst thou guide

Arcturus, with his sons?”

Some of the greatest poets of antiquity were in a manner fascinated, by

the grandeur of that science, (though they accompanied it with mystical

notions,) which furnishes the sublimest objects in nature to the

contemplation of the astronomer.

Ovid tells us, he wished to take his flight among the stars:

—-—-—“Juvat ire per alta

Astra; juvat, terris et inerti sede relictis,

Nube vehi, validique humeris insistere Atlantis.”[37]

_Metamorph._ lib. xv.

It delights me to soar among the lofty stars; it delights me to leave

the earth and this dull habitation, to be wafted upon a cloud, and to

stand upon the shoulders of the mighty Atlas.
