She is just trying to sound intelligent. Really, it's a form of chastity display, a way to posture her choices about who to sleep with as if she is in the driver's seat and that these adhere to some higher principles. It all depends on age really. I'd guess that this woman is probably beginning to shift gears toward the 'settling down' phase of life. Without knowing for sure, she's probably in her late 20s or early 30s, jumping between guys as she tries to establish herself professionally in the world. Now that she's escaped the university context where she had virtually zero standards for who she slept with, she's caught up mostly in the cultural conversation around dating that happens online. Now she's trying to situate herself in that space as someone who has a clear idea about what she wants and is seeking validation about her suddenly-high standards for worldview in the man she makes a nest with. The concept of a woman offering another woman advice on dating is absurd to begin with, not to mention that nothing a woman says with respect to some intellectual framework for deciding about a man holds any water at all. The thing to understand is the transition. In her former life, this same woman was likely to run from any guy who brought up books at the bar, and instead went home with the guy who bought her enough drinks to get her drunk, or had the right shoulder-to-waist ratio, or was getting enough attention from *other* women. She'd fuck the guy who made fun of her for bringing books up and called her a dork. Female dating advice is basically going to be confusion, by nature. Here's a firm rule: don't listen to women who give you advice about dating women. They almost invariably don't know what attracts them to men. Not only that, but her estrus cycle means it will change on a sliding scale as the month goes along. The thing that gets you home on a Thursday night might get you a cold shoulder on Saturday. With the exception of a very few women, the idea that one could judge me on the basis of which philosophers I like is laughable. She rules out Aristotle. It should be clear that she isn't even basing her choices on the thought of these philosophers. She is making a tenuous connection between a category of guy that she's formed from her experience talking to men who have read those philosophers. What does this tell you? It means the philosophy is a proxy. She doesn't give a shit what the guy thinks. She is doing some folk statistics about whether her personal Chad likes this or that thinker.
