The notion of history of philosophy is initiated by Boche��ski by presentation of the notion of history itself which, ac��cording to him for the fact of treating the past (���that what happened���), has two meanings: subject meaning (past events) and object meaning (historioso��phy). Both of them can be further divi��ded into two parts: history of facts and history of doctrines. History of philo��sophy is a typical history of doctrines. The second element of the name ���histo��ry of philosophy���- which is philosophy-is etymologically linked to wisdom, pre��sent in numerous meanings: in antiquity its was simply a synonim of science. In the Middle Ages we observe division of human knowledge to revealed know��ledge and natural knowledge, the lat��ter one, in its aspect of exploring the ultimate principles and causes is called philosophy. In modern times philoso��phy was questioned at all or the entire science was included in its scope. For that reason Boche��ski establishes the set of topics which are constantly pre��sent in the history of philosophy and which can be classified as strictly philo��sophical issues.
