Time: 10:00 AM – 12:00 PM
Location: Pacifica Christian High School – 20th Street Seminar Room

Lyceum Student Seminar
There has been a lot of controversy recently involving words like gender, sex, male, female, man, and woman. This talk will provide some clarity, by explaining the competing definitions of these terms. We will see how the word gender has several different meanings, which makes it difficult to have clear, productive conversations on these issues. We’ll also consider reasons in favor of the traditional understandings of terms like man and male, according to which men are adult human males, and biological sex is defined in terms of gamete production. Finally, we’ll consider why these issues matter so much to our culture, as well as whether sex is binary, and whether sex change is theoretically possible.

Attendance is by invite only.
