Life is a copiously branching bush, continually pruned by the grim reaper of extinction, not a ladder of predictable progress. Stephen Jay Gould More Quotes by Stephen Jay Gould More Quotes From Stephen Jay Gould I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops. Stephen Jay Gould peacepeopleinteresting We cannot win this battle to save species and environments without forging an emotional bond between ourselves and nature as well - for we will not fight to save what we do not love. Stephen Jay Gould emotionalfightingnature 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. Stephen Jay Gould applessciencemean Life is short, and potential studies infinite. We have a much better chance of accomplishing something significant when we follow our passionate interests and work in areas of deepest personal meaning. Stephen Jay Gould life-is-shortpassionatechance The center of human nature is rooted in ten thousand ordinary acts of kindness that define our days. Stephen Jay Gould human-naturekindnessordinary 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 Stephen Jay Gould iceatheistyears Humans are not the end result of predictable evolutionary progress, but rather a fortuitous cosmic afterthought, a tiny little twig on the enormously arborescent bush of life, which if replanted from seed, would almost surely not grow this twig again. Stephen Jay Gould tinyprogresslittles When people learn no tools of judgment and merely follow their hopes, the seeds of political manipulation are sown. Stephen Jay Gould politicalpeoplereligion The enemy is not fundamentalism; it is intolerance. In this case, the intolerance is perverse since it masquerades under the "liberal" rhetoric of "equal time." But mistake it not. Stephen Jay Gould intolerancemistakeenemy 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). Stephen Jay Gould failingobjectivitytests What you see is that the most outstanding feature of life's history is a constant domination by bacteria. Stephen Jay Gould bacteriadominationoutstanding The most important scientific revolutions all include, as their only common feature, the dethronement of human arrogance from one pedestal after another of previous convictions about our centrality in the cosmos. Stephen Jay Gould arrogancehumilityscience The real tragedy of human existence is not that we are nasty by nature, but that a cruel structural asymmetry grants to rare events of meanness such power to shape our history. Stephen Jay Gould rare-eventstragedyreal Organisms [...] are directed and limited by their past. They must remain imperfect in their form and function, and to that extent unpredictable since they are not optimal machines. We cannot know their future with certainty, if only because a myriad of quirky functional shifts lie within the capacity of any feature, however well adapted to a present role. Stephen Jay Gould quirkylyingpast Science is an integral part of culture. It's not this foreign thing, done by an arcane priesthood. It's one of the glories of the human intellectual tradition. Stephen Jay Gould intellectualscienceculture 'Creation science' has not entered the curriculum for a reason so simple and so basic that we often forget to mention it: because it is false, and because good teachers understand exactly why it is false.

Stephen Jay Gould atheismlife-isreligion Facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome.
