Chapter 6 explores the role of the imagination as an individual and communal phenomena, in enabling individuals to recognise who is of a common nature, the basis by which they are useful to each other, a faculty called commonality. The relation of imagination and intellect, crucial to Maimonides and preoccupying parts of the TTP’s discussion of philosophy and theology, will be first grounded in the epistemology of the Ethics. Then, focused on the TTP, explores the socially beneficial effects that can follow from the use of the imagination in bringing communities together, through Spinoza’s account of the prophet. What does it mean then that, in Spinoza’s irony-laden remark, ‘today, so far as I know, we have no prophets’ (TTP 1.7)? The figure of Jesus Christ, presented as both a prophet and a philosopher in the TTP, is one way of thinking through some of the possibilities and ambivalences of the philosopher’s use of reason and imagination. Then, through a late assessment of the relation between the individual and the collective in Benjamin, Lukács and Spinoza, it concludes on the pre-eminence of shared imaginings to communal identity, and the underlying difficulty for group identities in also producing capable, self-determining individuals.
