(This article is part of a project by Trans/Form/Ação: Unesp Philosophy Journal. It is the  Authorial Philosophy Dossier, to be published in 2022.) In this paper I argue that the ecological approach to perception provides resources to overcome the causal argument against disjunctivism. According to the causal argument, since the brain states that proximally cause the perceptual experience and the corresponding hallucinatory one can be of the same type, there would be no good reason to reject that the perceptual experience and the corresponding hallucinatory experience have fundamentally the same nature. Disjunctivism in respect to the nature of the experience would then be false. I identify three assumptions that support the causal argument: the indistinguishability assumption, the linearity assumption and the duplication assumption. According to the ecological approach to disjunctivism, these assumptions should be rejected, opening up room for a version of disjunctivism that I call ‘Ecological Disjunctivism’. Perceptual episodes are extended over time and supervenient to the organism-environment system. They can be distinguished from the ‘corresponding’ hallucinations because the former result from a controlled process of attunement to the environment, whereas hallucinations are passive and insensible to the exploratory activities of the perceptual system. Finally, the ecological disjunctivism, inasmuch as it is immune to the causal argument, is more advantageous in relation to the negative and positive disjunctivisms.
