This article is historical and philosophical in nature. Its purpose is to outline the most important trends and problems in the 19th-century Spanish philosophy. This philosophy has not yet been the subject of deeper analyses, especially in Polish literature on the subject. This is a major oversight, because the nineteenth century is the time of the impressive growth of modern social, political, legal, moral and intelectual structures in Spain. An important role in their development was played by Spanish philosophers and their reception of modern European philosophy and science. The reception was accompanied by numerous disputes and discussions about the condition of the Spanish culture and its possible development directions.
