The brain is a world consisting of a number of unexplored continents and great stretches of unknown territory.
As long as our brain is a mystery, the universe, the reflection of the structure of the brain, will also be a mystery.
Like the enotmologist 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.
Unfortunately, nature seems unaware of our intellectual need for convenience and unity, and very often takes delight in complication and diversity.

In adult centers the nerve paths are something fixed, ended, immutable. Everything may die, nothing may be regenerated.
Physical pain is easily forgotten, but a moral chagrin lasts indefinitely.
It is idle to dispute with old men. Their opinions, like their cranial sutures, are ossified.

That which enters the mind through reason can be corrected. That which is admitted through faith, hardly ever.
It is notorious that the desire to live increases as life itself shortens.
What a cruel irony of fate, to pair together, like Siamese twins united by the shoulders, scientific adversaries of such contrasting character!
To solicit the aid of luck is like stirring muddy water to bring objects submerged at the bottom to the top where they can be seen. Every worker would to well to tempt their good luck. Nevertheless, we should not depend on it too much.
Even granting that the genius subjected to the test of critical inspection emerges free from all error, we should consider that everything he has discovered in a given domain is almost nothing in comparison with what is left to be discovered.
