The ideas gained by men before they are twenty-five are practically the only ideas they shall have in their lives.
Interpretation
Early ideas shape a person's lifelong beliefs and perspectives.
William James suggests that the foundational ideas and beliefs that individuals develop before the age of twenty-five significantly influence their worldview for the rest of their lives. This highlights the critical importance of education and experiences during youth, as these formative years largely determine how one perceives and interacts with the world as an adult.
In practice
In a graduation speech, you might say this quote to emphasize the importance of lifelong learning.
Many persons nowadays seem to think that any conclusion must be very scientific if the arguments in favor of it are derived from twitching of frogs' legs (especially if the frogs are decapitated) and that, on the other hand, any doctrine chiefly vouched for by the feelings of human beings (with heads on their shoulders) must be benighted and superstitious.
The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.
All the higher, more penetrating ideals are revolutionary. They present themselves far less in the guise of effects of past experience than in that of probable causes of future experience, factors to which the environment and the lessons it has so far taught us must learn to bend.

As there is no worse lie than a truth misunderstood by those who hear it, so reasonable arguments, challenges to magnanimity, and appeals to sympathy or justice, are folly when we are dealing with human crocodiles and boa-constrictors.
I did not clip the wings of my daughter to fly.
That is the future, and it is probably nearer than we think. But our primary problem as universities is not engineering that future. We must rise above the obsession with quantity of information and speed of transmission, and recognize that the key issue for us is our ability to organize this information once it has been amassed - to assimilate it, find meaning in it, and assure its survival for use by generations to come.
They spent the first three years of school getting you to pretend stuff and then the rest of it marking you down if you did the same thing.
The study of history is the best medicine for a sick mind; for in history you have a record of the infinite variety of human experience plainly set out for all to see; and in that record you can find yourself and your country both examples and warnings; fine things to take as models, base things rotten through and through, to avoid.
The ancient superficial idea of the uniform and progressive growth of the human personality has remained unaltered, and the erroneous belief has persisted that it is the duty of the adult to fashion the child according to the pattern required by society.
Humans aren't as good as we should be in our capacity to empathize with feelings and thoughts of others, be they humans or other animals on Earth. So maybe part of our formal education should be training in empathy. Imagine how different the world would be if, in fact, that were 'reading, writing, arithmetic, empathy.'
