The day is November 24, 2009.
From the HUUmanists email list:
Remember that today is a holy day to Humanists, Unitarian Universalists, and all others who hold sacred our rapidly increasing knowledge of our own precious human nature, and especially its relation to the rest of the universe. One hundred fifty years ago today, on November 24, 1859, Charles Darwin opened the gates of heaven with his publication of "On the Origin of Species by Natural Selection, or the Preservation of Favoured Races in the Struggle for Life," and suddenly a great light shone down upon us all. Our understanding of ourselves has grown rapidly ever since, is growing today, and will continue to grow forever. Humanity will never be the same again.
Amen and hallelujah!
Spinoza was born on this day in 1632.
Happy Birthday to you, Spinoza. Another reason for a Humanist celebration.
Spinoza is best known for his Ethics, a monumental work that presents an ethical vision unfolding out of a monistic metaphysics in which God and Nature are identified. God is no longer the transcendent creator of the universe who rules it via providence, but Nature itself, understood as an infinite, necessary, and fully deterministic system of which humans are a part. Humans find happiness only through a rational understanding of this system and their place within it.
