I question whether man can ascend through knowledge. He can ascend technologically, but psychologically, inwardly, inside the skin, is there any ascent at all? If the mind doesn’t free itself from the known – not from this known to that known, or from that to that, which is all still within the field of the known – we are just moving in the past, modified and so on. If there is no freedom from the known, we are prisoners to this. We may make better transportation, better this and better that, but it is still within that field.
