Extraction Tools

Famous quotes containing the words extraction and/or tools:

    Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo problems.
    Rudolf Carnap (1891–1970)

    Think of the tools in a tool-box: there is a hammer, pliers, a saw, a screwdriver, a rule, a glue-pot, nails and screws.—The function of words are as diverse as the functions of these objects.
    Ludwig Wittgenstein (1889–1951)
