"In offering to the public a book on Humanity to Animals, I am sensible that I lay myself open to no small portion of ridicule; independent of all the common dangers to which authors are exposed. To many, no doubt, the subject which I have chosen will appear whimsical and uninteresting, and the particulars into which it is about to lead me ludicrous and mean. From the reflecting, however, and the humane I shall hope for a different opinion and of these the number, I trust, among my countrymen is by no means inconsiderable. The exertions which have been made to diminish the sufferings of the prisoners, and to better the condition of the poor, the flourishing state of charitable institutions; the interest excited in the nation by the struggles for the abolition of the slave-trade; the growing detestation of religious persecution—all these and other circumstances induce me to believe that we have not been retrograding in Humanity during the present century: and I feel the more inclination and encouragement to execute the task to which I have set myself, inasmuch as humanity to animals presents itself to my mind as having an important connection with humanity towards mankind."
