• Como usted sabe, las percepciones obtenidas por los sentidos no son más que sensaciones impresas en nuestro sistema nervioso. Se requiere una actividad intelectual peculiar para pasar de una sensación nerviosa a la concepción de un objeto externo, que la sensación ha suscitado. Las sensaciones de nuestros nervios de los sentidos son meros símbolos que indican ciertos objetos externos, y por lo general sólo después de una práctica considerable adquirimos el poder de sacar conclusiones correctas de nuestras sensaciones con respecto a los objetos correspondientes.

• Cuando el joven Galileo, entonces estudiante en Pisa, observó un día durante el servicio divino un candelabro que oscilaba hacia adelante y hacia atrás, y se convenció a sí mismo, contando su pulso, de que la duración de las oscilaciones era independiente del arco a través del cual se movía, ¿quién podía saber que este descubrimiento nos permitiría con el tiempo, por medio del péndulo, alcanzar una exactitud en la medición del tiempo que hasta entonces se consideraba imposible, y permitiría al marino azotado por la tormenta en los océanos más lejanos determinar en qué grado de longitud estaba navegando?

• Just as a physicist has to examine the telescope and galvanometer with which he is working; has to get a clear conception of what he can attain with them, and how they may deceive him; so, too, it seemed to me necessary to investigate likewise the capabilities of our power of thought.

• Isolated facts and experiments have in themselves no value, however great their number may be. They only become valuable in a theoretical or practical point of view when they make us acquainted with the law of a series of uniformly recurring phenomena, or, it may be, only give a negative result showing an incompleteness in our knowledge of such a law, till then held to be perfect.

• The total quantity of all the forces capable of work in the whole universe remains eternal and unchanged throughout all their changes. All change in nature amounts to this, that force can change its form and locality, without its quantity being changed. The universe possesses, once for all, a store of force which is not altered by any change of phenomena, can neither be increased nor diminished, and which maintains any change which takes place on it.

• During the first half of the present century we had an Alexander von Humboldt, who was able to scan the scientific knowledge of his time in its details, and to bring it within one vast generalization. At the present juncture, it is obviously very doubtful whether this task could be accomplished in a similar way, even by a mind with gifts so peculiarly suited for the purpose as Humboldt's was, and if all his time and work were devoted to the purpose.

• In speaking of the work of machines and of natural forces we must, of course, in this comparison eliminate anything in which activity of intelligence comes into play. The latter is also capable of the hard and intense work of thinking, which tries a man just as muscular exertion does.

• The most startling result of Faraday's Law is perhaps this.
