The article analyses two main economic trends (liberalism and keynesism) in the context of possible theoretical and practical answers they can give to questions related to the essence and causes of economic crises and counteraction against them. The author shows a significant connection between the appearance of global crises and domination of liberal thinking among economic theoreticians, practitioners and politicians. This connection is illustrated by historical examples of economic crises. The author also presents the reasons for crises (usually liberal thinking) and ways of counteraction against them (indicating that the keynesism recipes are the most effective). Finally, the author states that in present political conditions, Polish economy is unlikely to quickly and successfully oppose the dangers resulting from the existence of crises phenomena as there is a fundamental ideological obstacle, which is liberal government, rejecting all keynesism recipes for an economic crisis.
