what happened to your idea of a group reading the PI? I would be interested. Did you mean a face to face group, or you want posts on this forum?

Wittgenstein can be considered anti-modernist. Alessandra Tanesini's book Wittgenstein, a feminist interpretation, draws out the sense of loneliness and isolation that comes from modernity, not to mention the dissociation from the world around us. Tanesini critiques exclusive ideas of community drawing on her understanding of Wittgenstein, so wanting to overcome the borders set up around 'us' against 'them'. Think of Jacinda Ardern after the Christchurch attacks, "they are us!"
Heidegger too critiques modernity, eg his essay on calculative thinking, but Heidegger also has some dubious credentials.
