Hilary Putnam
Truth, realism, and the rejection of metaphysical realism — the pragmatic realist who repeatedly rebuilt his position when honesty required it

Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Hilary Putnam
Standard linear physical time.
Space
Hilary Putnam
Standard substantival space.
Matter
Hilary Putnam
Standard substantival matter; natural realism about the world.
Observer
Hilary Putnam
Plural embodied observers; mediated but real contact with the world. No metaphysical agency in the late natural-realist position.
Energy
Hilary Putnam
Standard physics.
Information
Hilary Putnam
Information conserved at the world-scale; personal soul not part of the philosophical framework, though the late Putnam engaged Jewish categories.
Internal Tensions
Where each persona's working synthesis strains against itself.
Putnam's public reversals (scientific realism → internal realism → natural realism) were criticized as instability and praised as honesty. The late engagement with Jewish religious philosophy was not, on his own account, in tension with the natural-realist position; how successfully the synthesis holds together is a continuing scholarly question.
