An object exists independent of our perception or conception of it. Michael Dummett is against this stance and calls it “colourless reductionism”.
Interestingly it is, in my opinion, precisely that reality is “colourless” that our minds colour it. It is the necessary part of our being conscious of our reality. And again, it is precisely because we erroneously supplement to the reality with minds that perhaps we need to reduce (remove) what was added to it.
