I think that common usage, when carefully considered, will be found to admit this definition. Suppose a nihilist blows up a railway train containing an emperor and other persons: it will no doubt be held correct to say simply that his intention was to kill the emperor; but it would be thought absurd to say that he `did not intend' to kill the other persons, though he may have had no desire to kill them and may have regarded their death as a lamentable incident in the execution of his revolutionary plans.
