Freud took up the uncanny in his essay of 1919 on the topic, arguably his greatest, most fruitful, and enduring contribution to the study of culture and nature. This chapter identifies its eco-cultural aspects that he neglected, especially his reading of what he calls “a naïve, but extraordinarily uncanny story” that he “came across” about crocodilecrocodiles and a table with carved crocodile legs. This chapter argues that the uncanny is the return to the repressed that brings into the open in the present what is in the past and long forgotten and opens a pathway to hope in and for the future. It also critiques the gender politics, ecoculture and psycho- and femo- political ecology of a late twentieth-century Australian eco-feminist’s recount of her encounter with a monstrous crocodile in an uncanny swamp. It concludes by asking the question what is religion? and answers that religion is the uncanny without the boundaries of mere reason. The uncanny does not have reason and has absented itself from it. The uncanny swamp for Thoreau is religion in his definition as “where our love is.” Religion is love for places and places that love, such as swamps for Thoreau in which he found hope.
