My aim is to reconstruct Kitarō Nishida’s logic of basho using contemporary non-classical logic. In this essay, as part of that process, I aim to interpret the concept of basho, as it originally appeared in the essay Basho (1924), as a phase space – a kind of multidimensional set – or the power set of said space. I will adopt the idea of phase space (or its representation in purely logical terms, the possible worlds model) as the model for the reconstruction of the logic of basho.
