Huemer has defended phenomenal conservatism, the epistemological view that it is reasonable to assume that things are as they appear, except when there are positive grounds for doubting this.[10][11]
Huemer defended reincarnation in his 2021 paper "Existence Is Evidence of Immortality".[12] He has argued that immaterial souls exist,[5] and in 2022, he debated Graham Oppy on the topic.[13]
On the ethics of eating meat, Huemer has commented that "In the overwhelming majority of actual cases, meat eaters do not have any reasons that could plausibly be claimed to justify the pain and suffering caused by their practice."[14]
In 2016, he debated Bryan Caplan on the ethical treatment of animals, including insects.[15] Regarding killing insects, he has argued that they are not raised in horrible conditions like animals in factory farms and that animal farming requires killing more insects, claiming that it is "much less likely that insects feel pain".[16]
His 2019 book, Dialogues on Ethical Vegetarianism, is a series of dialogues on the ethics of eating meat. Peter Singer, who wrote the foreword to the book, commented that "In the future, when people ask me why I don't eat meat, I will tell them to read this book."[17][18]
Huemer is an advocate of ostroveganism, a plant-based diet with the addition of oysters and other bivalves.[19][20] In a 2023 interview, Huemer stated that it is "fair game" to eat animals without brains such as scallops and that he also occasionally eats pasture-raised eggs.[21] He has argued that is impossible to inflict pain on bivalves, because they do not have a brain.[22]
