“Men may be very learned, and yet very miserable; it is easy to be a deep geometrician, or a sublime astronomer, but very difficult to be a good man. I esteem, therefore, the traveller who instructs the heart, but despise him who only indulges the imagination. A man who leaves home to mend himself and others, is a philosopher; but he who goes from country to country, guided by the blind impulse of curiosity, is only a vagabond.” Oliver Goldsmith book The Citizen of the World The Citizen of the World (1760–1761), Letter VII.
“The better sort here pretend to the utmost compassion for animals of every kind. To hear them speak, a stranger would be apt to imagine they could hardly hurt the gnat that stung them: they seem so tender and so full of pity, that one would take them for the harmless friends of the whole creation; the protectors of the meanest insect or reptile that was privileged with existence. And yet, would you believe it? I have seen the very men who have thus boasted of their tenderness, at the same time devouring the flesh of six different animals toasted up in a fricassee. Strange contrariety of conduct! they pity and they eat the objects of their compassion.” Oliver Goldsmith book The Citizen of the World The Citizen of the World (1760–1761), Letter XV https://books.google.it/books?id=cIELAAAAIAAJ&pg=PA44.
