Remember that [scientific thought] is the guide of action; that the truth which it arrives at is not that which we can ideally contemplate without error, but that which we may act upon without fear; and you cannot fail to see that scientific thought is not an accompaniment or condition of human progress, but human progress itself.
Interpretation
Scientific thought provides a reliable framework for making decisions that drive human progress.
This quote emphasizes the vital role of scientific thought as a guiding principle for human action. It suggests that the truths derived from scientific inquiry are not only theoretical but are fundamental in enabling us to make decisions without fear, thereby underscoring that scientific thought is integral to true human progress rather than merely a supplementary aspect of it.
In practice
In a speech about the importance of research and innovation, I could use this quote to highlight how scientific thinking advances society.
The aim of scientific thought, then, is to apply past experience to new circumstances; the instrument is an observed uniformity in the course of events. By the use of this instrument it gives us information transcending our experience, it enables us to infer things that we have not seen from things that we have seen; and the evidence for the truth of that information depends on our supposing that the uniformity holds good beyond our experience.
Into this, for good or ill, is woven every belief of every man who has speech of his fellows. A awful privilege, and an awful responsibility, that we should help to create the world in which posterity will live.
This sense of power is the highest and best of pleasures when the belief on which it is founded is a true belief, and has been fairly earned by investigation.
We may always depend on it that algebra, which cannot be translated into good English and sound common sense, is bad algebra.
It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.
Creationists eagerly seek a gap in present-day knowledge or understanding. If an apparent gap is found, it is assumed that God, by default, must fill it.
A discovery is like falling in love and reaching the top of a mountain after a hard climb all in one, an ecstasy not induced by drugs but by the revelation of a face of nature that no one has seen before and that often turns out to be more subtle and wonderful than anyone had imagined.
The very large brain that humans have, plus the things that go along with it - language, art, science - seemed to have evolved only once. The eye, by contrast, independently evolved 40 times. So, if you were to 'replay' evolution, the eye would almost certainly appear again, whereas the big brain probably wouldn't.
In the process of natural selection, then, any device that can insert a higher proportion of certain genes into subsequent generations will come to characterize the species.
Science is a human activity, and the best way to understand it is to understand the individual human beings who practise it. Science is an art form and not a philosophical method. The great advances in science usually result from new tools rather than from new doctrines. ... Every time we introduce a new tool, it always leads to new and unexpected discoveries, because Nature's imagination is richer than ours.
To promote the healing response, you must get past all the grosser levels of the body - cells, tissues, organs and systems -- and arrive at a junction point between mind and matter, the point where consciousness actually starts to have an effect.
