Anarchism In , Capetillo identifies herself as a
socialist anarchist, arguing for collective ownership of "advances, discoveries, and inventions" while opposing state control. This reflected the views of the majority of Puerto Rican workers at the time. According to researcher Stephanie Rivera Berruz, Capetillo was drawn to anarchism because it was "a political philosophy put into action". Valle Ferrer states that she was also influenced by "Romantic anarchists" like
Errico Malatesta and
Leo Tolstoy. Philosophically, Capetillo believed that humans are naturally kind and support equality but that they are corrupted by the social systems in which they live. Drawing on anarcho-syndicalist principles, she supported organized labor movements and the general strike as a tool for disrupting these systems. Because of her anti-state views, Capetillo opposed the
independence movement in Puerto Rico, viewing it as an oppressive force. She criticized the Puerto Rican
Unionist Party, accusing them of being "egoists, exploiters, and aristocrats" who oppressed the island's workers. Rivera Berruz argues that Capetillo's views on nationhood and the state were influenced by Puerto Rico's colonial status and her own status as a transnational migrant.
Women's rights and free love Capetillo is often considered the first feminist writer from Puerto Rico. According to Rivera Berruz, Capetillo articulated feminist ideas long before the rise of what philosopher
Francesca Gargallo considers the
mainstream feminist movement in the 1960s. She is also frequently associated with
anarcha-feminism, a movement opposing government and
patriarchal authority. In her work, she draws links between women's liberation and organized labor, advocating for an egalitarian system for men and women workers. She also calls for greater sexual freedom for women, describing women's sexual desire as being as natural as hunger and sleep. She believed that motherhood was an essential aspect of womanhood, stating after giving birth to her first child that "a woman will always be a mother, even if she doesn't have children". Capetillo advocated for
free love. In her view, free love was the union of two people unrestrained by legal contracts and social conventions about families. She defined love as a union of free people, with free love being marked by mutual love, respect, and support. If either partner fell out of love, Capetillo believed that the relationship should end. She called marriage the "prostitution of love". In her view, marriage forced women into passive roles and prevented them from exiting relationships, limiting their freedom and hence their ability to love. Many anarchists advocated for free love, both in Puerto Rico and abroad. However, Capetillo's emphasis on women's exploitation in critiquing the institution of marriage was unique among anarchists and labor activists.
Religion Capetillo was a Christian, but she denounced organized religion throughout her life. In an essay from , she accuses the church of "trickery" and "hypocrisy", as well as wealth hoarding. She believed that
Mass and other religious ceremonies were primarily ways for wealthy women to show off their clothing and jewelry. Capetillo's ideal Christian tended to the poor and sick instead of attending Mass. While she was baptized as a child, she never baptized her own children, calling it a "denigrating mark". Valle Ferrer argues that Capetillo's Christian beliefs were influenced by Tolstoy, who was a
Christian anarchist. Capetillo was also influenced by
Kardecist spiritism. She believed in
reincarnation, a spiritual body distinct from the physical, and a "plurality of habitable worlds". begins with a quote from spiritist
Camille Flammarion, a collaborator and friend of
Allan Kardec. Kardecist spiritists of the nineteenth century often called for
liberty, equality, and fraternity, and researcher Carmen Ana Romeu Toro states that Capetillo was drawn to spiritism because it championed these values, among others.
Education Capetillo viewed education as being essential to human liberation, allowing people to unlearn harmful ideas they received from society. In one essay from , Capetillo argues for universal education without class or gender distinctions. She also advocated specifically for women's education. In her view, women's education would bring greater financial and intellectual independence. She believed that women's education should include the arts, sciences, and humanities, as well as discussion of women's sexual desires.
Health and hygiene In the collection , Capetillo recommends various health and personal hygiene practices. These include exercise, daily baths, and Eastern-inspired meditation. She also advocates for moderation in drinking and smoking, as well as a
vegetarian diet. At her New York boarding house, she served vegetarian food. ==Legacy==
