All this reading about how, or if, we know there are other consciousnesses out there has got me thinking about the way I think. The truth is I don’t think I have ever had the thought ‘that’s another consciousness’, but then I don’t think I have had a thought along the lines of ‘that’s a table’ either. If you stopped to think about it then you would say yes that’s a person or a table, but most of the time we just assume so much knowledge in our daily interactions with the world. Perhaps there is a point as a child when we don’t take such things for granted, however if that is the case it is before my memory starts.
Sartre at the moment is discussing the work of Hegel who apparently thought that we know there is another consciousness present because somehow the other consciousness affects our self-consciousness. I’m not entirely sure I understand the argument for how that works.
