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.

In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.' I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

People, as curious primates, dote on concrete objects that can be seen and fondled. God dwells among the details, not in the realm of pure generality. We must tackle and grasp the larger, encompassing themes of our universe, but we make our best approach through small curiosities that rivet our attention - all those pretty pebbles on the shoreline of knowledge. For the ocean of truth washes over the pebbles with every wave, and they rattle and clink with the most wondrous din.

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 reveal ourselves in the metaphors we choose for depicting the cosmos in miniature.

Revolutions usually begin as replacements for older certainties, and not as pristine discoveries in uncharted terrain.

I am, somehow, less interested in the weight and convolutions of Einstein__ brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops.

Objectivity cannot be equated with mental blankness; rather, objectivity resides in recognizing your preferences and then subjecting them to especially harsh scrutiny _ and also in a willingness to revise or abandon your theories when the tests fail (as they usually do).

Our planet is not fragile at its own timescale and we, pitiful latecomers in the last microsecond of our planetary year, are stewards of nothing in the long run.

This new consensus seemed so compelling that Ernst Mayr, the dean of modern Darwinians, opened the ashcan of history for a deposit of Geoffrey's ideas about anatomical unity.

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*?

Current utility and historical origin are different subjects.

Obsolescence is a fate devoutly to be wished, lest science stagnate and die.

Science tries to record and explain the factual character of the natural world, whereas religion struggles with spiritual and ethical questions about the meaning and proper conduct of our lives. The facts of nature simply cannot dictate correct moral behavior or spiritual meaning.

There are no shortcuts to moral insight. Nature is not intrinsically anything that can offer comfort or solace in human terms -- if only because our species is such an insignificant latecomer in a world not constructed for us. So much the better. The answers to moral dilemmas are not lying out there, waiting to be discovered. They reside, like the kingdom of God, within us -- the most difficult and inaccessible spot for any discovery or consensus.

I remember when we found the first population of living Cerion agassizi in central Eleuthera. Our hypothesis of Cerion's general pattern required that two predictions be affirmed (or else we were in trouble): this population must disappear by hybridization with mottled shells toward bank-interior coasts and with ribby snails toward the bank-edge. We hiked west toward the bank-interior and easily found hybrids right on the verge of the airport road. We then moved east toward the bank-edge along a disused road with vegetation rising to five feet in the center between the tire paths. We should have found our hybrids but we did not. The Cerion agassizi simply stopped about two hundred yards north of our first ribby Cerion. Then we realized that a pond lay just to our east and that ribby forms, with their coastal preferences, might not favor the western side of the pond. We forded the pond and found a classic hybrid zone between Cerion agassizi and ribby Cerions. (Ribby Cerion had just managed to round the south end of the pond, but had not moved sufficiently north along the west side to establish contact with C. agassizi populations.) I wanted to shout for joy. Then I thought, "But who can I tell; who cares?" And I answered myself, "I don't have to tell anyone. We have just seen and understood something that no one has ever seen and understood before. What more does a man need?
