Like the entomologist in search of colorful butterflies, my attention has chased in the gardens of the grey matter cells with delicate and elegant shapes, the mysterious butterflies of the soul, whose beating of wings may one day reveal to us the secrets of the mind.
Interpretation
This quote compares the pursuit of understanding the mind to an entomologist's search for butterflies, emphasizing the beauty and mystery of the brain's secrets.
Santiago Ramon Y Cajal uses the metaphor of an entomologist searching for colorful butterflies to illustrate the intricate and delicate process of exploring the human mind. Just as butterflies symbolize beauty and transformation, the 'butterflies of the soul' represent the profound insights and mysteries that lie within our cognitive processes, suggesting that through careful study, we may uncover the deeper secrets of human consciousness.
In practice
In a lecture about neuroscience, one could use this quote to illustrate the beauty of studying the brain.
In my own view, some advice about what should be known, about what technical education should be acquired, about the intense motivation needed to succeed, and about the carelessness and inclination toward bias that must be avoided is far more useful than all the rules and warnings of theoretical logic.
The worst part is not in making a mistake but in trying to justify it, instead of using it as a heaven-sent warning of our mindlessness or our ignorance.
As long as our brain is a mystery, the universe, the reflection of the structure of the brain will also be a mystery.
Intellectual beauty is sufficient unto itself, and only for it rather than for the future good of humanity does the scholar condemn himself to arduous and painful labors.
Artificial selection turned the wolf into the shepherd, and the wild grasses into wheat and corn. In fact, almost every plant and animal that we eat today was bred from a wild, less edible ancestor. If artificial selection can work such profound changes in only ten or fifteen thousand years, what can natural selection do operating over billions of years? The answer is all the beauty and diversity of life.
The fact that all Mathematics is Symbolic Logic is one of the greatest discoveries of our age; and when this fact has been established, the remainder of the principles of mathematics consists of the analysis of Symbolic Logic itself.
Forty years as an astronomer have not quelled my enthusiasm for lying outside after dark, staring up at the stars. It isn't only the beauty of the night sky that thrills me. It's the sense I have that some of those points of light are the home stars of beings not so different from us, daily cares and all, who look across space with wonder, just as we do.
I need scarcely say that the beginning and maintenance of life on earth is absolutely and infinitely beyond the range of all sound speculation in dynamical science. The only contribution of dynamics to theoretical biology is absolute negation of automatic commencement or automatic maintenance of life.
If others would but reflect on mathematical truths as deeply and as continuously as I have, they would make my discoveries.
Contaminated water is not a problem limited to Flint. Think of New Jersey, where school fountains were found to contain unsafe levels of lead. Or the EPA's 33,000 superfund sites, which are highly-polluted areas that require long-term clean-up operations. The problem is so large that it feels insurmountable.
