There can be no evidence against materialism because evidence is by definition material, so if any evidence of any kind is found, it would support materialism.
However, there is no evidence for materialism - that is, there has never been found any material outside consciousness. As I sit here in this room, I do not see, hear or taste and etc any matter outside of my being conscious of it. I can not find any matter with intrinsic existence, that is, matter that exists independent of my being aware of it, or matter I can infer from its effects on matter I observe.
I can leave the room and return, and things are as I left them. I need to be again conscious of them to establish they exist, and I can only claim they existed while I was out - but I can't prove it without direct or indirect observation of consciousness.
I can make these claims:
I can not prove there is any matter outside of consciousness.
I make moment by moment concessions to 'reality' - concessions so I don't walk into walls and default on my mortgage. By concessions I refer to this line from William Wordsworth "Our birth is but a sleep and a forgetting." where by 'birth' I believe the poet is referring to our constant rising into contents of mind and by 'sleep and forgetting' a necessary error.
