    1. The chapter discusses the ultimate failure of the structure that is now known as the Great Wall, and how it not only failed to protect China from barbarians, but in many ways hastened its destruction.

      This answered my questions about the importance of the Great Wall of China. I always believed it was a barrier to the north.

    1. is China at this point in time modern?

      China is becoming modernized at this point in many ways because they are incorporating different customs into their dynasty but perhaps it was not as easy as it was portrayed in the reading.

    1. Studies of great ape behavior show that they are good at cooperating in situations where there is no potential of deception, but behave egotistically in situations where there are motives for deception, suggesting that their "lack of cooperativeness" is not a lack of a cognitive ability at all, but rather a necessary adaptation to a society full of deception.[citation needed] This suggests that human cooperativeness began when proto-humans began to successfully avoid competition, which is also supported by the fact that the oldest evidence of care for the long-term sick and disabled are from shortly after the first emigration of hominins out of Africa about 1.8 million years ago

      successfully avoiding competition was key to humans doing super well vs the egotistical, competitive, & deceiving ways of apes

      being able to cooperate and get around deception/defection was key to humans doing so well

    1. If the Klensin Standards Track [Page 19] RFC 5321 SMTP October 2008 recipient is known not to be a deliverable address, the SMTP server returns a 550 reply, typically with a string such as "no such user - " and the mailbox name (other circumstances and reply codes are possible).

      Will the entire transaction be canceled? "Transaction" in the name of this a section implies yes, but what if all the recipients are valid?

      See replies below but the answer is no; an RCPT command is specified for each recipient in the mail data, these RCPT commands will be evaluated in sequence,, and any SMTP (error) notifications will be sent to the address in the MAIL FROM command (which is not necessarily the same as the mail data's From: header).

    2. If the verb is initially accepted and the 354 reply issued, the DATA command should fail only if the mail transaction was incomplete (for example, no recipients),

      How could this specific scenario be even possible? It just said in the previous paragraph that

      If there was no MAIL, or no RCPT, command, or all such commands were rejected, the server MAY return a "command out of sequence" (503) or "no valid recipients" (554) reply in response to the DATA command.

    1. humans are creatures who crave a story

      in relation to the language of silence (and Bacon's use of color), we must consider we may be reading too deeply into some of these works. how can we draw conclusions and meaning out of a painting, let alone stories older than most trees and from completely different societies without projecting our own feelings and experiences onto them? with this, can we trust that much of human experience over all known time are similar enough to trust and put weight into these projections?
