He argued that we never observe space directly, and goes on to suggest that therefore we can't assume it exists. I merely pointed out that the same logic applies to all observations, and therefore we can't assume *from observation* that anything exists. The existence of space, matter, etc, are all hypotheses we have formed to account for what happens inside our brains, assuming it does happen inside our brains (another hypothesis).
His argument is similar to saying "I can't see atoms, therefore they don't exist." -- You received this message because you are subscribed to the Google Groups "Everything List" group.
