e given in your own spirit. For every one, as I think, must see that
astronomy compels the soul to look upwards and leads us from this world
to another.

Every one but myself, I said; to every one else this may be clear, but
not to me.

And what then would you say?

I should rather say that those who elevate astronomy into philosophy
appear to me to make us look downwards and not upwards.

What do you mean? he asked.

You, I replied, have in your mind a truly sublime conception of our
knowledge of the things above. And I dare say that if a person were to
throw his head back and study the fretted ceiling, you would still think
that his mind was the percipient, and not his eyes. And you are very
likely right, and I may be a simpleton: but, in my opinion, that
knowledge only which is of being and of the unseen can make the soul
look upwards, and whether a man gapes at the heavens or blinks on the
ground, seeking to learn some particular of sense, I would deny that he
can learn, for nothing of that sort is matter of science; his soul is
looking downwards, not upwards, whether his way to knowledge is by water
or by land, whether he floats, or only lies on his back.

I acknowledge, he said, the justice of your rebuke. Still, I should like
to ascertain how astronomy can be learned in any manner more conducive
to that knowledge of which we are speaking?

I will tell you, I said: The starry heaven which we behold is wrought
upon a visible ground, and therefore, although the fairest and most
perfect of visible things, must necessarily be deemed inferior far to
the true motions of absolute swiftness and absolute slowness, which are
relative to each other, and carry with them that which is contained in
them, in the true number and in every true figure. Now, these are to be
apprehended by reason and intelligence, but not by sight.

True, he replied.

The spangled heavens should be used as a pattern and with a view to that
higher knowledge; their beauty is like the beauty of figures or pictures
excellently wrought by the hand of Daedalus, or some other great artist,
which we may chance to behold; any geometrician who saw them would
appreciate the exquisiteness of their workmanship, but he would never
dream of thinking that in them he could find the true equal or the true
double, or the truth of any other proportion.

No, he replied, such an idea would be ridiculous.

And will not a true astronomer have the same feeling w
