Unfailing ever, must there ever be
An infinite force of matter all sides round.
75
And in these problems, shrink, my Memmius, far
From yielding faith to that notorious talk:
That all things inward to the centre press;
And thus the nature of the world stands firm
With never blows from outward, nor can be
5
Nowhere disparted- since all height and depth
Have always inward to the centre pressed
(If thou art ready to believe that aught
Itself can rest upon itself ); or that
The ponderous bodies which be under earth
10
Do all press upwards and do come to rest
Upon the earth, in some way upside down,
Like to those images of things we see
At present through the waters. They contend,
With like procedure, that all breathing things
15
Head downward roam about, and yet cannot
Tumble from earth to realms of sky below,
No more than these our bodies wing away
