Textausschnitt: () The all-sufficiency of common-sense knowledge deprives the human mind of its full development. The person of common sense understands to live, so that intelligence is always harnessed to practical ends. Only the Greek breakthrough freed the mind from its traces and bridle to explore its own inner thrust - which has been seen to be unlimited. The restriction to short - term practicality simply rules out all such development.

One problem with these sciences, at least in their present forms, is that they claim to be 'value-free.' But human living, as chapter 26 showed, is inescapably involved with values. Therefore a value-free science cannot be the final form of human knowing.

The morality derivable from the structure of knowing had to remain general. But actual moral choices are between particular courses of action, to be performed by a particular person, in a particular situation.

Logic proceeds by syllogism. But each syllogism needs two premises to generate one conclusion. If those two premises are to be logically demonstrated, they will require four premises; and those four, eight prior premises; and those eight, sixteen; and so on. In short, scientific and logical knowing cannot ground itself.

... Gödel. He showed that in any closed logical system, a question may be asked that cannot be answered within that system. Any set of premises can be shown to generate problems which require, for their solution, an additional premise, and so a larger logical system. The same will be true of that larger system, and so on. The upshot is that no logical system can ground itself.
