Hands-on experience at the critical time, not systematic knowledge, is what counts in the making of a naturalist. Better to be an untutored savage for a while, not to know the names or anatomical detail. Better to spend stretches of time just searching and dreaming.

Known as the biosphere to scientists and as the creation to theologians, all of life together consists of a membrane around earth so thin that it cannot be seen edgewise from a satellite yet so prodigiously diverse that only a tiny fraction of species have been discovered and named.

Each of these [bacterial] species are masterpieces of evolution. Each has persisted for thousands to millions of years. Each is exquisitely adapted to the environment in which it lives, interlocked with other species to form ecosystems upon which our own lives depend in ways we have not begun even to imagine.

Biology has finally opened up to achieve a unifying embrace of all its disciplines. We're seeing the renaissance of what could be called scientific natural history, which makes available the groundwork - the foundation work - of what is actually on the Earth.

I doubt that most people with short-term thinking love the natural world enough to save it.

Real biologists who actually do the research will tell you that they almost never find a phenomenon, no matter how odd or irrelevant it looks when they first see it, that doesn't prove to serve a function. The outcome itself may be due to small accidents of evolution.

The human race is not divided into two opposing camps of good and evil. It is made up of those who are capable of learning and those who are incapable of doing so.
