摘要：In the present article we aim to illustrate the mediated character of inferences designated as being immediate. We analyze immediate inferences through equivalence, respectively deducted immediate inferences based on the oppositional hexagon relations. For both types of inferences, the illustration is made using both Aristotelian and composite sentences. The result of this approach indicates that, in the cases of both of the two types of immediate inferences being discussed, it comes as a mediated inference, namely a two-premise inference, following the hypothetic-categorical inference model and the disjunctive-categorical model from the logic of composite sentences. In conclusion, the most frequently used immediate inferences are built on three hypothetical dyadic relations and three disjunctive relationships, and the composite sentence (which expresses the relationship) is the absent, but tacitly assumed, premise. We refer to premise without which the conclusion could not be established. The absence of the premise that expresses the logical relation between the sentences involved in the inference ensures the immediate aspect of the approach. So, in reality, immediate inferences are incomplete, mediated approaches.
