According to the realization criterion that distinguishes deductive argument from inductive argument, the realized necessity relation between the premises and the conclusion defines deductive argument. In this case, 'invalid deductive argument' is an oxymoron. According to the intention criterion, the intended necessity relation between the premises and the conclusion defines deductive argument. In this case, 'invalid deductive argument' is not an oxymoron. In this paper, we will argue for the intention criterion. The realization criterion cannot classify an elliptical argument without referring to the intention represented in the argument. It cannot distinguish an argument from a set of propositions that is not an argument either. On the other hand, the problem that an intention may not be recognized in an argument can be resolved by referring to the principle of charity. Moreover, by distinguishing the expressions showing the conviction or the attitude to the argument from the intention of the argument, we conclude that the intention criterion successfully distinguishes deductive argument from inductive argument.

Hong and Yeo choose the intention criterion instead of the realization criterion for distinguishing deductive and inductive argument in their paper. This study aims to criticize their argument. I contend that their argument confuses argument reconstruction and argument classification[evaluation], and is making the mistake of utilizing the realization criterion when attempting to make up for the difficulties of the intention criterion. Also, most logicians, including Hong and Yeo, support the division of the argument into deductions, inductions, and bad arguments. Here I insist on a binary division of only deduction and induction. Finally, I argue that there is no need to teach the distinction between deduction and induction when teaching logic.

The purpose of this study is to attempt a convergent study by analyzing modern funk ceramic artworks through 'Irony', which was mainly used in rhetoric and literature. The irony has come to modern times and has embraced the type of irony by Jung Keut-Byul, a literary critic who has discovered that the classifications and definitions are different from each other, and who has solved these problems and has newly classified the irony (the irony of oxymoron, the irony as a counterstatement, the irony of dramatic turn, the irony as a poetic truth) as a framework for analyzing the works of 20th century punk potters. As a result, the formative language found in funk ceramic art had many similarities with the irony of duality of surface and reality, and its humorous and comic character was more prominent than the heavy, melodramatic tone shown in literature. It was also found that the media characteristics and craft properties of ceramic art, such as clay and glaze, have become the drivers for ceramic sculptors to draw attention in funk art.

Among the weather conditions on the Korean Peninsula, Changma is a notable phenomenon. This is because substantial amount of the precipitation on the Korean Peninsula tends to happen during the Changma season. But there are times when this tendency falls into whims. That's the case when it doesn't rain or rains only little during the Changma season. The Korea Meteorological Administration (KMA) describes this phenomenon as 'Dry Changma' - meaning . However, 'Dry Changma' is often regarded as an instance of contradicto in adjecto. Since the general public believe that 'Changma' means . This confusion often leads to distrust in meteorologists. In this paper, we would like to propose a reasonable solution to this conundrum by employing the conceptual resources of contemporary philosophy. First of all, I will make explicit the meaning of 'Changma' that the public and meteorologists think of. And then a brief explanation of the concept of natural kinds will be presented and the argument will be made that Changma is a natural kind. Next, we will discuss a view on natural kind terms advanced by Saul Kripke, a renowned philosopher. We will argue that in Kripke's view, the general public's thought that 'Dry Changma' is contradicto in adjecto is not correct. This will eventually lead to the conclusion that the meteorologist usage of 'Changma' is the correct one, which is thereby to be adopted by the public.
