If it be violence when he who suffers
Co-operates not with him who uses force,
These souls were not on that account excused;

For will is never quenched unless it will,
But operates as nature doth in fire
If violence a thousand times distort it.

Hence, if it yieldeth more or less, it seconds
The force; and these have done so, having power
Of turning back unto the holy place.

If their will had been perfect, like to that
Which Lawrence fast upon his gridiron held,
And Mutius made severe to his own hand,

It would have urged them back along the road
Whence they were dragged, as soon as they were free;
But such a solid will is all too rare.

And by these words, if thou hast gathered them
As thou shouldst do, the argument is refuted
That would have still annoyed thee many times.

But now another passage runs across
Before thine eyes, and such that by thyself
Thou couldst not thread it ere thou wouldst be weary.

I have for certain put into thy mind
That soul beatified could never lie,
For it is near the primal Truth,

And then thou from Piccarda might’st have heard
Costanza kept affection for the veil,
So that she seemeth here to contradict me.

Many times, brother, has it come to pass,
That, to escape from peril, with reluctance
That has been done it was not right to do,
