ABSTRACT
Our knowledge of the world constitutes a problem not in the field of knowledge but in that of description. Philosophy is neither to increase our knowledge of the world nor to reveal its ultimate constituents; for increasing and revealing are, in this context, primarily the tasks of common sense and science. Moreover, perceptual variation and error can be unmasked only by procedures such as looking more carefully, listening harder, trying to touch, asking others, in short by more sense experience. Thus people have a problem whether sensibly formulated or not which appears to have ramifications in both metaphysics and epistemology, although strenuous attempts have been made to answer it in such a way as to eliminate all metaphysical implications. People claims there was a landbridge four million years ago between Malacca and Sumatra, our analysis reiterates this claim too and verification or falsification depends on the expert acceptance or rejection of the induction from the present geological evidence.
