Oswald Kulpe 
Introduction to Philosophy [PDF ebook] 
A Handbook for Students of Psychology, Logic, Ethics, Aesthetics and General Philosophy

First published in 1927, this translation of Kulpe’s ‘Einleitung in die Philosophie’, 1895, covered psychology, logic, ethics, esthetics and general philosophy. The author adopted a uniform approach of positivity, interest and impartiality, aiming his work at a wider public than students of philosophy. The volume was intended as an elementary but complete guide to philosophy, past and present and included facts and arguments previously confined to philosophical encyclopaedias.
