“On Certainty is a feminist, philosophical meditation on love, loss, and ways of knowing—through history, through philosophy, technology, and through the body. Like the taxidermied deer sculpture covered with crystal spheres that the book makes reference to, On Certainty considers the blurring of the real and the virtual, the conceptual and the embodied. There are no simplistic borders, no clear edges. There is instead beauty and lyricism in language, the accumulative power of repetition and re-contextualizing of phrases and imagery, and there are provocations, thrilling in all their ontological possibilities.”

“In On Certainty the Tyrant, the Philosopher and the Poet are triangulated in a struggle for meaning’s definitions within history’s conglomerations and the troubling immediacy of socio-political and ecological disaster. In shimmering fractionalized form Kelsey summons past lives and a projection of possible futures into an event horizon of feminist reckoning. This fierce and elegant saga untangles speculative tautologies to understand dynamic contingency in prismatic, mesmerizing transmissions. I wish the Poet the upper hand in regardening the world.”
