Environmental Uncanny
The term is used to describe a new relationship with the environment now that the language of the sublime no longer seems appropriate with the end of the idea of human mastery over the Earth (Ghosn 2020, p.62). The environmental uncanny «pertains to nonhuman beings» and has «no human referents at all» (Ghosh 2016, p.32), it is connected to but somehow different from the «sublime».

Soft Spaces
«Soft spaces are the fluid areas between such formal processes where implementation through bargaining, flexibility, discretion and

Speculative Fabulation
Donna Haraway, with reference to Joshua LaBare defines Speculative Fabulation as a «mode of attention, a theory of history, and a practice of worlding» that considers the «conceivable, possible, inexorable, and logical»
