Nebulæ can be selected so that an insensible gradation shall take place from a coarse cluster like the Pleiades down to a milky nebulosity like that in Orion, every intermediate step being represented. This tends to confirm the hypothesis that all are composed of stars more or less remote.

In the humanist ideal, the mainstream is where interesting debate, the generating of new ideas and creativity take place. In rational society this mainstream is considered uncontrollable and is therefore made marginal. The centre ground is occupied instead by structures and courtiers.
John Ralston Saul
Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb.
Winston Churchill
