Just for purposes of thinking ahead, I see that this coming weekend (3/21) we will reach the end of book 4, and we'll probably want to recap the general theme on the "love" passages. Please think about whether there are any summary points we ought to cover and let us know in the thread. I will set up the text later today. Here are Munro's notes on the remaining topics, which he makes pretty clear are probably united by the theme that it isn't divine gods that take the lead in these issues:
1209-1232: according as the seed of the man or woman prevails at conception, the child is more like to the one or to the other; and this is so whether the child be male or female.
1233-1277: it is not the gods who grant or withhold offspring: conception depends on the due assortment of man and wife.
1278-1287: often by her own virtues, from no divine interposition, a woman without personal attractions will endear herself to her husband.
