To things immortal Time can do no wrong,

And that which never is to die for ever must be young.

Yet, what a treasure is this:

My inheritance! how wide and fair!

Time is my estate; to Time I’m heir.

Wilhelm Meister: Carlyle.

“Time is almost a human word, and change entirely a human idea: in the system of nature we should rather say progress than change. The sun appears to sink in the ocean in darkness, but rises in another hemisphere; the ruins of a city fall, but they are often used to form more magnificent structures, as at Rome; but even when they are destroyed, so as to produce only dust, nature asserts her empire over them, and the vegetable world rises in constant youth, and in a period of annual successions, by the labours of man, providing food, vitality, and beauty upon the wreck of monuments which were once raised for purposes of glory, but which are now applied to objects of utility.”

As this beautiful passage was written by Sir Humphry Davy nearly three-and-thirty years since, the above use of the word progress had nothing to do with the semi-political sense in which it is now commonly employed. Nevertheless, there occur in the writings of our great chemical philosopher occasional views of the advancement of the world in knowledge, and its real authors, with which the progressists of the present day fraternise.

At the above distance, Davy wrote in the following vein: “In the common history of the world, as compiled by authors in general, almost all the great changes of nations are confounded with changes in their dynasties; and events are usually referred either to sovereigns, chiefs, heroes, or their armies, which do, in fact, originate entirely from different causes, either of an intellectual or moral nature. Governments depend far more than is generally supposed upon the opinion of the people and the spirit of the age and nation. It sometimes happens that a gigantic mind possesses supreme power, and rises superior to the age in which he is born: such was Alfred in England, and Peter in Russia. Such instances are, however, very rare; and in general it is neither amongst sovereigns nor the higher classes of society that the great improvers and benefactors of mankind are to be found.”—Consolations in Travel, pp. 34, 35.

Brilliant as was Davy’s own career, it had its life-struggles: his last days were embittered with sufferings, mental as well as physical; and in these moments he may have written these somewhat querulous remarks.
