Playing with constructs of identity, gender, sexuality, reproduction, biology and culture are the cornerstones of sci fi - here are some thoughts, suggestions and a request for discussion. Le Guin - Left Hand of Darkness - extraordinary ideas that reach out beyond the accepted views of gender and sexuality. Le Guin then goes on to examine, investigate and criticise her own language use in "The Language of the Night". Le Guin maintains the highest standards of literary integrity by never letting herself off the hook. Suzette H. Elgin - Native Tongue and The Judas Rose - conjures a world where contact with aliens creates the need to have "native" undestanding of language and culture. Elgin was a Professor of Linguistics. These books entralled me and challenge readers to see connections between language, thought and potentials within culture. Joanna Russ - The Female Man, The Two of Them, We Who Are About To... Writing that challenges biological determinism. Women's Press - published some extraordinary books in the 1970's and 80's. Any other additions or thoughts on this subject ?
