 So construed, FP comes with built-in “heavy-duty”, as opposed to “light-duty”, ontological commitments (Langland-Hassan 2020). Light duty TTists actively eschew or are otherwise agnostic about whether FP is committed to the existence of entities with the properties that are referred to in our everyday FP attributions. Several variants of TT, including instrumentalist and fictionalist variants, that assume our everyday sense-making practice has only light-duty ontological commitments (Egan 1995; Graham &amp; Horgan 1988; Schwitzgebel 2002, 2013; Demeter 2013).
