Then at this point, my boys, let us take heed, and be on our guard against deceptions. I will not again repeat that the friend is the friend of the friend, and the like of the like, which has been declared by us to be an impossibility; but, in order that this new statement may not delude us, let us attentively examine another point, which I will proceed to explain: Medicine, as we were saying, is a friend, or dear to us for the sake of health?
Yes.
And health is also dear?
Certainly.
And if dear, then dear for the sake of something?
Yes.
And surely this object must also be dear, as is implied in our previous admissions?
Yes.
And that something dear involves something else dear?
Yes.
