We pass through this world but once. Few tragedies can be more extensive than the stunting of life, few injustices deeper than the denial of an opportunity to strive or even to hope, by a limit imposed from without, but falsely identified as lying within.

We are here because one odd group of fishes had a peculiar fin anatomy that could transform into legs for terrestrial creatures; because the earth never froze entirely during an ice age; because a small and tenuous species, arising in Africa a quarter of a million years ago, has managed, so far, to survive by hook and by crook. We may yearn for a ‘higher answer’– but none exists

We have become, by the power of a glorious evolutionary accident called intelligence, the stewards of life's continuity on earth. We did not ask for this role, but we cannot abjure it. We may not be suited to it, but here we are.

Intelligence is too complex and multifaceted a thing to reduce to any single dimension.

Wonder and knowledge are both to be cherished.

¿Por qué el origen de la vida pluricelular se dio en forma de un corto pulso a través de tres faunas radicalmente diferentes , y no como un aumento lento y continuo de complejidad? La historia de la vida es infinitamente fascinante, infinitamente curiosa, pero ciertamente no es la sustancia de nuestros pensamientos y esperanzas usuales.

The idea of decimation as a lottery converts the new iconography of the Burgess Shale into a radical view about the pathways of life and the nature of history. ... May our poor and improbable species find joy in its new-found fragility and good fortune! Wouldn't anyone with the slightest sense of adventure, or the most weakly flickering respect for intellect, gladly exchange the old cosmic comfort for a look at something so weird and wonderful - yet so real - as *Opabinia*?

Yes, the world has been different ever since Darwin. But no less exciting, instructing, or uplifting; for if we cannot find purpose in nature, we will have to define it for ourselves.

Among people I have met, the few whom I would term “great” all share a kind of unquestioned, fierce dedication; an utter lack of doubt about the value of their activities (or at least an internal impulse that drives through any such angst); and above all, a capacity to work (or at least to be mentally alert for unexpected insights) at every available moment of every day of their lives.
