We are asleep. Our Life is a dream. But we wake up sometimes, just enough to know that we are dreaming.

- IC 5146 (Wikipedia)
IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470. It shines at magnitude +10.0/+9.3/+7.2. Its celestial coordinates are RA 21h 53.5m , dec +47° 16′. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years.

- Ludwig Wittgenstein (plato.standford.edu)
Considered by some to be the greatest philosopher of the 20th century, Ludwig Wittgenstein played a central, if controversial, role in mid-20th-century analytic philosophy. He continues to influence, and incur debate in, current philosophical thought in topics as diverse as logic and language, perception and intention, ethics and religion, aesthetics and culture, and even political thought. Furthermore, a central factor in investigating Wittgenstein’s works is the multifarious nature of the project of interpreting them; this leads to untold difficulties in the ascertainment of his philosophical substance and method.
