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.</style></abstract><work-type><style face="normal" font="default" size="100%">State</style></work-type><custom2><style face="normal" font="default" size="100%">Papers</style></custom2><custom3><style face="normal" font="default" size="100%">15</style></custom3></record></records></xml>
