• We may lay it down as an incontestible axiom, that, in all the operations of art and nature, nothing is created; an equal quantity of matter exists both before and after the experiment; the quality and quantity of the elements remain precisely the same; and nothing takes place beyond changes and modifications in the combination of these elements. Upon this principle the whole art of performing chemical experiments depends: We must always suppose an exact equality between the elements of the body examined and those of the products of its analysis.

• As ideas are preserved and communicated by means of words, it necessarily follows that we cannot improve the language of any science, without at the same time improving the science itself; neither can we, on the other hand, improve a science without improving the language or nomenclature which belongs to it.

• He tenido una vida bastante larga, sobre todo muy feliz, y creo que se me recordará con cierto pesar y tal vez deje alguna reputación tras de mí. ¿Qué más puedo pedir? Los acontecimientos en los que me veo envuelto me evitarán probablemente los problemas de la vejez. Moriré en plena posesión de mis facultades, y ésa es otra ventaja que debo contar entre las que he disfrutado. Si tengo algún pensamiento angustioso, es el de no haber hecho más por mi familia; ser incapaz de darles a ellos o a usted alguna muestra de mi afecto y mi gratitud es ser realmente pobre.

  Life, Gratitude, Regret

• We think only through the medium of words. Languages are true analytical methods. Algebra, which is adapted to its purpose in every species of expression, in the most simple, most exact, and best manner possible, is at the same time a language and an analytical method. The art of reasoning is nothing more than a language well arranged.

• The impossibility of separating the nomenclature of a science from the science itself, is owing to this, that every branch of physical science must consist of three things; the series of facts which are the objects of the science, the ideas which represent these facts, and the words by which these ideas are expressed. Like three impressions of the same seal, the word ought to produce the idea, and the idea to be a picture of the fact.
