The great Library at Daylight Atheism has been outfitted for an auspicious occasion. Merry bunting drapes the tall shelves of books, balloons congregate near the ceiling, and waiters quietly circulate bearing trays of drinks. Already the symposium is in full swing, and philosophers from every era and society in human history are circulating around the room and chatting animatedly: ancient Greeks in togas and sandals, Enlightenment Europeans - the men in frock coats and powdered wigs and the women in elegant gowns - colonial Americans, Indians in saffron robes, East Asians from the Neo-Confucian period in robes and topknots, Muslim Sufis in white kaffiyehs and dusky hijabs, and a few modern luminaries in cardigan sweaters, t-shirts and blue jeans. A few senior philosophers are holding discourse with their younger colleagues beneath plaster busts that suspiciously resemble them.

A podium has been set up near the tall picture windows at one end of the room, beneath a banner reading, "Ubi Dubium Ibi Libertas". The windows offer a picturesque view of a verdant and sunny garden below, where a few early arrivals seem to have organized a friendly game of football on the lawn.

Your humble host, Ebonmuse, takes the podium and surveys the room. He rings a spoon against the side of a glass to call the meeting to order, and once everyone's attention has turned to the podium, clears his throat and begins to speak.

Until next time, fellow philosophers and friends!"
