The article deals with philosophical basis of Czech author Laidslav Klíma focused mainly on its relation with logic, as it is hinted on the beginning of his first philosophical work "World as consciousness and nothing". First theses of work are compared with the similar passages in Schopenhauer's books and the relation is analyzed.
A special attention is paid to Klíma's refusing of logic in its traditional form and to his attempt to replace it with so called "natural logic". The handed down originality of Klíma's thinking is shown as a specific interpretation of Schopenhauer's work, which often abandons its basis in unacceptable way in its own meaning.
Therefore the originality of Klíma's thinking could be caused by misinterpretation of its own pattern in some way.
