Captive organisms are out of context, they don’t have a natural environment (they might as well be dead as far as an ecologist is concerned) Henry David Thoreau (1854) Walden “Book of Life” metaphor Holmes Rolston (1985) “Vanishing Book of Life” Humans are just beginning to be able to read it, but its pages are tattered and torn, and entire chapters have been ripped out. Need to save as much as possible (conservation biology), but also must READ it (ecology) before it is gone. Other Earthlings were here before us and have a right to exist, too.

Proper motivation to do science is curiosity. How do things work? Assume an organized reality exists and that objective principles can be formulated to reflect this natural order (not faith based). Common misconception that “truth” and “proof” and even “facts” exist. Nietzsche said “there are no facts, only interpretation.” Better to say facts include interpretation Nietzsche

Most people consider a “fact” as “what really happened.” However, Many “facts” are not so clean and simple -- most involve varying levels of interpretation. Consider, for example, the apparently simple fact that the Sun rises each morning. Daily we receive new evidence confirming this fact. We can be quite confident that the Sun will rise again tomorrow. References to sunrise and sunset are based on now defunct concept of a “flat Earth and moving Sun”. But our understanding of cosmic events is greatly enhanced when instead of thinking of the Sun as moving, it is viewed as fixed in space at the center of a solar system, and the Earth is interpreted as a rotating globe orbiting around a small star. Our vocabulary hasn't caught up -- clearly, we should refer to “sunrise” as “spinup” or “spindawn” and “sunset” as “spindown” or “spindusk.”
Observation and Experiment are vital.Scientists formulate hypotheses to explain repeatable events. A hypothesis is tested by confronting it with reality — if it fails, it is discarded and replaced with another, hopefully better, hypothesis. In time, a well supported hypothesis becomes a theory. The scientific method is self regulating: poor hypotheses are continually replaced with better ones as human knowledge expands and is improved. We benefit immensely from past genius.
