In this context 'present' means 'the here and now', the way we perceive or conceptualize the world momentarily.
Hm. It is still a bit odd to understand 'at base' as meaning 'fundamentally' in this context. I was thinking the same, that's why I asked.
No technical sense of 'at base' is intended by the author, I'm sure.
To assume this, we have to assume that perceptual processes at the cognitive level
play no part in the development of concepts, but only external sensorimotor information.
As I have been arguing throughout this book, I believe this assumption to be false. While
the elaborated concept of the present is structured in terms of such content, it is erroneous
to suggest that, at base, the concept of present is wholly derived from external sensorimotor
Thank you very much for your help.
