By P. Fletcher

positive arithmetic relies at the thesis that the that means of a mathematical formulation is given, now not by way of its truth-conditions, yet by way of what buildings count number as an evidence of it. even if, the that means of the phrases `construction' and `proof' hasn't ever been competently defined (although Kriesel, Goodman and Martin-Löf have tried axiomatisations). This monograph develops targeted (though now not totally formal) definitions of building and evidence, and describes the algorithmic substructure underlying intuitionistic common sense. Interpretations of Heyting mathematics and positive research are given.
The philosophical foundation of constructivism is explored completely in half I. the writer seeks to respond to objections from platonists and to reconcile his place with the important insights of Hilbert's formalism and common sense.
Audience: Philosophers of arithmetic and logicians, either educational and graduate scholars, really these drawn to Brouwer and Hilbert; theoretical machine scientists attracted to the foundations of practical programming languages and application correctness calculi.

Key notions are analyzed, similar to results, possible choices and performability. Carlson argues that consequentialism may be understood as a maximizing instead of a satisficing thought, and as temporally impartial instead of destiny orientated.

Isaac von Sinclair (1775–1815), deutscher Diplomat und Schriftsteller, unternimmt in seinem dreibändigen Hauptwerk ›Wahrheit und Gewissheit‹ (1811) eine systematische Darstellung der menschlichen Erfahrung. Der hier edierte Band 1 entwickelt die metaphysischen und anthropologischen Grundlagen. Im Ausgang vom höchsten Zweifel entwirft Sinclair eine Metaphysik der Erfahrung, die von einer spekulativen Logik zu Themen wie Gott, Bewusstsein, Leben und Körperlichkeit reicht.
