A mind which has once imbibed a taste for scientific inquiry, and has learnt the habit of applying its principles readily to the cases which occur, has within itself an inexhaustible source of pure and exciting contemplations.

The stars are the land-marks of the universe.

Every student who enters upon a scientific pursuit, especially if at a somewhat advanced period of life, will find not only that he has much to learn, but much also to unlearn.

The besetting evil of our age is the temptation to squander and dilute thought on a thousand different lines of inquiry.

Johann Wolfgang von Goethe

It can hardly be pressed forcibly enough on the attention of the student of nature, that there is scarcely any natural phenomenon which can be fully and completely explained, in all its circumstances, without a union of several, perhaps of all, the sciences.

The novel, in its best form, I regard as one of the most powerful engines of civilization ever invented.

Were I to pray for a taste which should stand me in good stead under every variety of circumstances and be a source of happiness and a cheerfulness to me during life and a shield against its ills, however things might go amiss and the world frown upon me, it would be a taste for reading.

...Nature builds up her refined and invisible architecture, with a delicacy eluding our conception, yet with a symmetry and beauty which we are never weary of admiring.

According to this view of the matter, there is nothing casual in the formation of Metamorphic Rocks. All strata, once buried deep enough, (and due TIME allowed!!!) must assume that state,-none can escape. All records of former worlds must ultimately perish.

Man is constituted as a speculative being he contemplates the world, and the objects around him, not with a passive indifferent eye, but as a system disposed with order and design.

Music and dancing (the more the pity) have become so closely associated with ideas of riot and debauchery among the less cultivated classes, that a taste for them, for their own sakes, can hardly be said to exist, and before they can be recommended as innocent or safe amusements, a very great change of ideas must take place.

Occurrences which according to received theories ought not to happen, are the facts which serve as clues to new discoveries
