Scope and content
91 Adelaide Road NW - Multipresence is placed on a basis of unintelligibility 'if we only envisage a quality acting through space as memory acts through time'. The analogies of space and time are 'the two indismissible extensions'. An annihilated star can be said to act when it is not, like matter 'can be said to act where it is not'. However 'presence is a very ill used notion. If a particle really do attract all others, it is present through out the universe...the presence of matter is the presence of all its qualities'. Henry Mansel is like the old logicians in the sense that he cannot separate the mathematical notion from infinite in quality and in everything. He would be glad to see anything of [Robert] Ellis's: during his illness he gained an 'enormous boon' from thinking about maths. without pen and paper; his preface to Bacon should be published.
