Pam Grossman lives on a quiet street in Park Slope, Brooklyn, next door to a Mexican restaurant that sells cheap burritos and $3 bottles of Mexican cola. She is soft-spoken with long, dark hair, wears punk black boots and is married to a man who collects “Star Wars” figurines, which he lines up on a dresser in their bedroom.

“My life is pretty ordinary,” she said one recent Monday as her cat, Remy, rubbed his whiskers against her hip.

Ms. Grossman was showing me her altar, a pastiche of moon pendants, candles, crystals and dried flowers. She calls herself a witch, and cast spells and teaches magical history. She has been named “the Terry Gross of witches” for “The Witch Wave” podcast she hosts. In June, she published “Waking the Witch: Reflections on Women, Magic, and Power.” And last weekend, she was an organizer of the Occult Humanities Conference hosted by New York University.

Today’s witches — those who identify more with feminism than burnings at the stake — are a part of the collective consciousness. For nearly two years, President Trump has called the investigation into Russia’s influence in the 2016 election a “witch hunt.” Witches are the subject of recent art exhibits. Even members of the Wing, the popular co-working space among well-heeled women in their 30s, refer to themselves as a coven.
