In science, parsimony is to prefer least complicated explanation for an observation. This is generally regarded as good when judging hypotheses.

The World as I see it - Einstein
"How strange is the lot of us mortals! Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people -- first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving...
"I have never looked upon ease and happiness as ends in themselves -- this critical basis I call the ideal of a pigsty. The ideals that have lighted my way, and time after time have given me new courage to face life cheerfully, have been Kindness, Beauty, and Truth. Without the sense of kinship with men of like mind, without the occupation with the objective world, the eternally unattainable in the field of art and scientific endeavors, life would have seemed empty to me. The trite objects of human efforts -- possessions, outward success, luxury -- have always seemed to me contemptible.
"My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities. I am truly a 'lone traveler' and have never belonged to my country, my home, my friends, or even my immediate family, with my whole heart; in the face of all these ties, I have never lost a sense of distance and a need for solitude..."
"This topic brings me to that worst outcrop of herd life, the military system, which I abhor... This plague-spot of civilization ought to be abolished with all possible speed. Heroism on command, senseless violence, and all the loathsome nonsense that goes by the name of patriotism -- how passionately I hate them!
"The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed. It was the experience of mystery -- even if mixed with fear -- that engendered religion. A knowledge of the existence of something we cannot penetrate, our perceptions of the profoundest reason and the most radiant beauty, which only in their most primitive forms are accessible to our minds: it is this knowledge and this emotion that constitute true religiosity. In this sense, and only this sense, I am a deeply religious man... I am satisfied with the mystery of life's eternity and with a knowledge, a sense, of the marvelous structure of existence -- as well as the humble attempt to understand even a tiny portion of the Reason that manifests itself in nature."

Union Line Cemetery
via goodreads
Union Line Cemetery
Lie the bones of a woman I loved
And those of a man I did not,
Though I am more like him than her.
Down a paved road off the federal highway
Slicing diagonally from Mobile,
The road turns sharply as if
It was meant to dead end.
But as if someone moved the gates
The road bends goes on precisely south
While the sun goes west away from the graves.
Marble benches wait through the undisturbed dust
For me to stop to pick sand spurs from my dress socks
And prick my fingers and remember I am alive.
While under clumps of low growing weeds,
Neat green grass and bare spots
These dead people rest in a Mississippi summer quiet,
As they do in winter beneath a midnight ice storm.
Dead, yes, they are dead,
But I am alive and they are why I am so.
They keep us, our families, ourselves alive.
I wonder if in a few years when I am dead,
Ashes tossed in the Mississippi,
Will I hold anyone connected or only be dust,
Forever blown about where the delta turns to sea?
