One thing which is suggested by the letters themselves is that Locke’s courtship was not rewarded as he hoped. “P.E.” welcomed love, but of a different sort from that which Locke offered her. She wanted a rarefied spiritual love. Locke was more ardent. He protested first with sadness and later with bitterness that her love was too cold. …
In another letter he assured “P.E.” that she was right in thinking he wished to come back to Oxford for the sake of people there; but he said she was wrong in putting her name after that of another person. However, he asked her to increase as much as she could that other person’s friendship for him. This other person was named in the letter as “Mr. T” and Locke was a little jealous of him. He told “P.E.” he could not believe that the new friendship between her and “Mr. T” would ruin their friendship, but it looks as if he was afraid that it might.
