3 Since Nature fails us in no needful thing,
Why want I means my inward self to see?
Which sight the knowledge of myself might bring,
Which to true wisdom is the first degree.

4 That Power, which gave me eyes the world to view,
To view myself, infused an inward light,
Whereby my soul, as by a mirror true,
Of her own form may take a perfect sight.

5 But as the sharpest eye discerneth nought,
Except the sunbeams in the air do shine;
So the best soul, with her reflecting thought,
Sees not herself without some light divine.

6 O light, which mak'st the light which makes the day!
Which sett'st the eye without, and mind within,
Lighten my spirit with one clear heavenly ray,
Which now to view itself doth first begin.

7 For her true form how can my spark discern,
Which, dim by nature, art did never clear,
When the great wits, of whom all skill we learn,
Are ignorant both what she is, and where?

8 One thinks the soul is air; another fire;
Another blood, diffused about the heart;
Another saith, the elements conspire,
And to her essence each doth give a part.

9 Musicians think our souls are harmonies;
Physicians hold that they complexions be;
Epicures make them swarms of atomies,
Which do by chance into our bodies flee.

10 Some think one general soul fills every brain,
As the bright sun sheds light in every star;
And others think the name of soul is vain,
And that we only well-mix'd bodies are.

11 In judgment of her substance thus they vary;
And thus they vary in judgment of her seat;
For some her chair up to the brain do carry,
Some thrust it down into the stomach's heat.

12 Some place it in the root of life, the heart;
Some in the liver, fountain of the veins;
Some say, she's all in all, and all in every part;
Some say, she's not contain'd, but all contains.
