Neuroscience is of no relevance to the problem of consciousness This touches upon a point I've been debating ever since joining forums - of reason understood as 'the relations of ideas'. The tendency of reductionism is to conflate the two kinds of causation, physical and logical: which is what we do when we say that 'the brain' acts in a particular way, and so 'produces' thought, because of physical causation. The 'because' of reasons - the 'space of reasons', it has been called - can't be explained in those terms, because it belongs to a different level of explanation. — Wayfarer
As we know from brain research, an idea is not caused by other ideas but by brain activities. These activities remain unknown to us for the majority, because only about ten percent of them are heaved into the consciousness. Let me explain: an idea cannot be a cause already because an idea is a representation, an imagination or a fiction. The sentence "I have an idea." is a symbolic narrative to which no real content corresponds. Neither is there an "I", nor can this "I" "possess" anything, such as an idea, all is just fiction.
This sentence is similar to another one, "I drag the file to the trash." Neither there is a recycle bin on the monitor, nor a file, nor is anything dragged, all just symbols. In reality, we operate the mouse and this triggers actions in the processor, on the hard disk and on the monitor. Similarly, if we say "The red knight has killed the black knight" in a computer game: it's all just symbols and representations.
