Philosopher: We should not disapprove of the unearthing of truths that we would rather not acknowledge or that, by their dissemination, might influence society in pernicious ways. Which one of the following conforms most closely to the principle stated by the philosopher? ['A poem need not adhere too strictly to the truth. Art is exempt from such requirements -- it matters only that the poem provoke a response in the reader.', "A physician should never withhold the truth from a patient, except in cases where depression induced by bad news might significantly affect the patient's recuperation.", 'A law enforcement officer should not act upon illegally obtained information, even though such action might, in some cases, result in a benefit to society.', 'Scientific research should not be restricted even if it could lead to harmful applications, such as the manufacture of sophisticated weapons.']
