@chj0 @rats @aetios I don't see why this would be an indicator of reasoning (never mind moral significance). Many animals seem to be doing quite complicated forms of reasoning, including ones that require them to e.g. simulate themselves as existing in time, which seems like a much more important feature for defining conciousness/self awareness.
I'm also not sure if you know that many people think in nonverbal ways – does this mean they are not doing reasoning?
