This is the second in my very occasional series about amusing Prefaces (the first is here). I came across this one while browsing John Walker’s 1847 translation of and commentary on Murray’s Compendium of Logic. It seems he wasn’t a happy bunny about his involvement in the project:
It is the misfortune of some Authors, that they are rather obliged to write what they can as they can; than allowed by circumstances to write what they might, and as they would.
[T]he manner in which I treat the subject, has been determined rather by necessity, than choice. Were I at liberty to pursue it according to the dictates of my own judgment, I certainly should not have taken for the basis of my work that piece, on which I offer a comment. I have briefly described, in the Appendix, the kind of treatise which I would gladly have attempted, if time and other circumstances had permitted me.
