I think our intelligence is a source of toxicity to nature and discomfort to ourselves unless our values are based on planetary values, are linked to the values of the rest of nature. Intelligence is not a license to trample. The proper role of intelligence in a planetary ecology is that of gardener, caregiver and maintainer of balance.
What history is, essentially, is a careening, out-of-control effort to find our way back to this state of primordial balance.
