As for fowling, during the last years that I carried a gun my excuse was that I was studying ornithology, and sought only new or rare birds. But I confess that I am now inclined to think that there is a finer way of studying ornithology than this. It requires so much closer attention to the habits of the birds, that, if for that reason only, I have been willing to omit the gun.
Henry David ThoreauMy excuse for not lecturing against the use of tobacco is, that I never chewed it; that is a penalty which reformed tobacco-chewers have to pay; though there are things enough I have chewed which I could lecture against.
Henry David ThoreauNo human being, past the thoughtless age of boyhood, will wantonly murder any creature which holds its life by the same tenure that he does.
