“Indeed, some of the problems commonly engaging the attention of philosophical thought appear to be deprived, not only of all importance, but of any meaning as well; a host of problems arise resting solely upon some ambiguity or upon a confusion of points of view, problems that only exist in fact because they are badly expressed, and that normally should not arise at all. In most cases therefore, it would in itself be sufficient to set these problems forth correctly in order to cause them to disappear, were it not that philosophy has an interest in keeping them alive, since it thrives largely upon ambiguities.”
