Works ’gainst its Maker.  Hence thou must infer
That love is germin of each virtue in ye,
And of each act no less, that merits pain. 
Now since it may not be, but love intend
The welfare mainly of the thing it loves,
All from self-hatred are secure; and since
No being can be thought t’ exist apart
And independent of the first, a bar
Of equal force restrains from hating that. 
     “Grant the distinction just; and it remains
The’ evil must be another’s, which is lov’d. 
Three ways such love is gender’d in your clay. 
There is who hopes (his neighbour’s worth deprest,)
Preeminence himself, and coverts hence
For his own greatness that another fall. 
There is who so much fears the loss of power,
Fame, favour, glory (should his fellow mount
Above him), and so sickens at the thought,
He loves their opposite:  and there is he,
Whom wrong or insult seems to gall and shame
That he doth thirst for vengeance, and such needs
Must doat on other’s evil.  Here beneath
This threefold love is mourn’d.  Of th’ other sort
Be now instructed, that which follows good
But with disorder’d and irregular course. 
     “All indistinctly apprehend a bliss
On which the soul may rest, the hearts of all
Yearn after it, and to that wished bourn
All therefore strive to tend.  If ye behold
Or seek it with a love remiss and lax,
This cornice after just repenting lays
Its penal torment on ye.  Other good
There is, where man finds not his happiness: 
It is not true fruition, not that blest
Essence, of every good the branch and root. 
The love too lavishly bestow’d on this,
Along three circles over us, is mourn’d. 
Account of that division tripartite
Expect not, fitter for thine own research.

CANTO XVIII

The teacher ended, and his high discourse
Concluding, earnest in my looks inquir’d
If I appear’d content; and I, whom still
Unsated thirst to hear him urg’d, was mute,
Mute outwardly, yet inwardly I said: 
“Perchance my too much questioning offends
But he, true father, mark’d the secret wish
By diffidence restrain’d, and speaking, gave
Me boldness thus to speak:  “Master, my Sight
Gathers so lively virtue from thy beams,
That all, thy words convey, distinct is seen. 
Wherefore I pray thee, father, whom this heart
Holds dearest! thou wouldst deign by proof t’ unfold
That love, from which as from their source thou bring’st
All good deeds and their opposite.”  He then: 
“To what I now disclose be thy clear ken
Directed, and thou plainly shalt behold
How much those blind have err’d, who make themselves
The guides of men.  The soul, created apt
To love, moves versatile which way soe’er
Aught pleasing prompts her, soon as she is wak’d
By pleasure into act.  Of substance true
Your apprehension forms its counterfeit,
