Isaac Asimov: Star Light.
Another murder story, but this time of a space traveller who kills to get access to millions, only to find he has space-jumped through hyperspace to the worst place he could have imagined.
Walt Whitman: I Sit and Look Out (1860)
Another gut wrencher:
'All these -- all the meanness and agony without end I sitting look out upon,
See, hear, and am silent.'
Peter Singer: The value of a pale blue dot (2009)
The title refers to the picture Voyager took of Earth from around 6 billion kilometres away, at the request of Carl Sagan. Here it is:
Earth is the tiny speck about half-way down the brown band (caused by diffraction by the camera's optics) on the right. (https://en.wikipedia.org/wiki/Pale_Blue_Dot).
Singer's argument is basically that we need to confront the truth of our insignificance in order to achieve the greatness of which we're capable.
