Biological evolution is a system of constant divergence without subsequent joining of branches. Lineages, once distinct, are separate forever. In human history, transmission across lineages is, perhaps, the major source of cultural change. Europeans learned about corn and potatoes from Native Americans and gave them smallpox in return.

For if you change from inhumanity to alms giving, you have stretched fourth the hand that was withered. If you withdraw from theaters and go to church, you have cured the lame foot. If you draw back your eyes from a harlot ... you have opened them when they were blind ... These are the greatest miracles.
John Chrysostom
I decide that sometimes definitions are wrong. Even if they're written in a dictionary. Identities aren't always separate and distinct. Sometimes they ARE wrapped up with others. Sometimes, for a few minutes, maybe they can even be shared. And if I am ever fortunate enough to return to Mr. Bender's garden, I wonder if the birds will see that piece of him that is wrapped up in me.

I've led a school whose faculty and students examine and discuss and debate every aspect of our law and legal system. And what I've learned most is that no one has a monopoly on truth or wisdom. I've learned that we make progress by listening to each other, across every apparent political or ideological divide.

I think that once people understand the great risks that climate change poses, they will naturally want to choose products and services that cause little or no emissions of greenhouse gases, which means 'low-carbon consumption.' This will apply across the board, including electricity, heating, transport and food.

If we take an unprejudiced view of the processes of consciousness, free from all the so-called association rules and theories, we see at once that an idea is no more an even relatively constant thing than is a feeling or emotion or volitional process. There exist only changing and transient ideational processes; there are no permanent ideas that return again and disappear again.
