Summary/Abstract: Bernard Bolzano presents in his work Wissenschaftslehre (1837) a definition of derivability among sentences. Tarski publishes his well-known definition of logical consequence almost one hundred years later. This article intends to prove that the Bolzano´s definition is fully satisfactory compared to the Tarski´s one, even though no attention was drawn to Bolzano´s definition at that time.
