Philosopher: Scientists talk about the pursuit of truth, but, like most people, they are self-interested. Accordingly, the professional activities of most scientists are directed toward personal career enhancement, and only incidentally toward the pursuit of truth. Hence, the activities of the scientific community are largely directed toward enhancing the status of that community as a whole, and only incidentally toward the pursuit of truth. The reasoning in the philosopher's argument is flawed because the argument ['improperly infers that each and every scientist has a certain characteristic from the premise that most scientists have that characteristic', 'improperly draws an inference about the scientific community as a whole from a premise about individual scientists', 'presumes, without giving justification, that the aim of personal career enhancement never advances the pursuit of truth', 'illicitly takes advantage of an ambiguity in the meaning of"self-interested"']
