Some years later, when he had recovered from the horrible mutilation to which he had been subjected by the uncle of Heloise, and his mind had acquired its usual strength, we find him at Paris, again attracting crowds by his brilliant lectures, and pouring forth books, and alas, another fatal one, Sic et Non.

The best edition of Abelard's letters is P. Abelardi et Heloiseae, conjugis ejus epistolae, ab erroribus purgatae et cum cod.

There is also an edition published in Paris in 1616, quarto, Petri Abelardi Heloiseae conjugis ejus opera cum praefatione apologetica ad persi conjugis ad persi et censura doctorum parisiensium ex editione Andreae Querquetani, which asked 158 questions on all kinds of subjects.
