앞에서 말씀드린 기술은 가철식 국부의치 하부구조(removable partial denture frame work)를 구강 내에 맞추기 전에 master cast에 맞추는 것을 기술한 것이다. 이 과정에서는 본 하부구조(frame work)의 외형을 유지하며 적합성을 높이는 것에 중점을 두어야 한다. 또한 제거된 금속의 양은 모형(cast)이 긁히지 않게 하기 위한 것이며, master cast 위에 주조체를 안착시키기에 필요한 양 만큼이어야 한다. 주조체의 치아 접촉면의 적합이 끝나면 가벼운 압박을 주며 광택을 낸다. 이러한 과정이 기공소에서 주의깊게 완수되면 치과의사는 하부구조를 최소한 짧은 시간에 구강 내에 맞출 수 있게 된다(그림 7).

One of the primary advantage of acrylic resin teeth is their ability to bond chemically to the denture base resins. But, occasionally, failure have been observed in which acrylic resin teeth break lose from the denture, indicating that chemical bonding does not always occur. The most probable explanation for this type of failure was the presence of a trace of wax remaining as a residue on the surfaces of the teeth after the boiling-out procedure which adgered to the tooth surface and prevented bonding. The purpose of this stdy was preparing the specimens of denture base resin with acrylic resin teeth that four treatment method to ridge lap portion of the tooth and investigated bond between the teeth and denture base resin with tensile strength. Compared results of tensile strength on test specimens were as follows: 1. The mean of strength among the four test groups showed the difference was significant enough(P 0.01). The order of its strength mean was methylene chloride treatment group, detergent solution treatment group, kerosene-ether treatment grgoup, boiling water only group. 2. In compared results between the wax eliminating method groups, there were significant difference between the boiling water only group and other groups(P 0.01), no significant difference were found in the wax eliminating method groups except boiling water only group(P 0.05).

루이 라벨의 ‘악의 현존과 고통’에 대한 긍정적인 해석 그리고 그 한계

이명곤(Lee, Myoung-gon) 대한철학회 2018 哲學硏究 Vol.145 No.-

루이라벨의 사상에서는 현대철학에서 거의 다루지 않고 있는 ‘선과 악’에 대한 주제가 매우 중요한 개념으로 등장하고 있다. 그의 사유에서 악의 개념은 ‘악이란 존재의 부족’이라는 스콜라철학의 소극적인 규정에서 출발하고 있지만, 세계에 현존하는 악이란 ‘삶과 가치’를 파괴하는 의지적인 힘으로, 즉 도덕적인 차원에서 보다 적극적인 의미로 규정하고 있다. ‘악의 현존(la présence du mal)’을 ‘세계의 스캔들(le scandale du monde)’로서 규정하는 그의 사유에는 모든 인간이 의지의 태도로서의 악의 가능성을 지니고 있으며, 세계와 인간사회에서의 악의 현존은 필연적인 것임을 말해주고 있다. 반면 악의 결과가 육체적 정신적인 ‘고통’으로서 나타나기에, 고통을 거부하고자 하는 인간의 ‘고통에 대한 태도’는 이러한 악을 극복하고자 하는 도덕적인 의지를 유발하게 한다. 악의 현존 앞에서 가지게 되는 ‘내적인 고통’인 ‘도덕적인 고뇌’는 그 자체 ‘도덕적인 존재’가 된다는 의식을 가지게 하고 여기서 자기만족을 가지게 되는 것이다. 비록 고통스럽지만 도덕적인 존재가 됨에 대한 자기만족과 행복감은 인간이 악의 현존에 맞서 이를 초극할 수 있는 유일한 계기이자 동기이다. 즉 라벨의 선과 악에 대한 사유는 ‘도덕 심리주의’에 기초해 있으며, 고통에 대한 거부와 도덕적 고뇌에 있어서의 ‘심리적 지평과 윤리적 지평의 일치’가 인간으로 하여금 끊임없이 악을 극복하고 선을 산출하도록 한다는 ‘윤리적 낙관론’을 가능하게 하고 있다. 이는 분명 스콜라 철학의 발전된 현대적인 적용이라고 할 수 있겠으나, 또한 ‘악을 유발하는 의지의 태도에 대한 구체적 양태의 분석’, ‘사회 속에 현존하는 악의 구체적인 양태들’ 그리고 이러한 악을 초극할 수 있는 ‘의지적인 노력의 다양한 양상’ 등에 대한 분석은 이루어지고 있지는 않다. 이러한 구체성의 부족은 선과 악에 관한 라벨의 사유가 여전히 소극적인 면모를 보이고 있다고 할 수 있다. In the philosophy of Louis Labelle, the subject of “good and evil”, which is rarely discussed in modern philosophy, emerges as a very important concept. In his reasoning, the notion of evil starts from a passive stipulation of the Scholastic philosophy of “the lack of being”, but he defined the evil, which actually exists in the world with more positive sense as a willing force destroying “life and values”. In his reasoning that defines “the presence of evil” as “le scandale du monde”, all humans have the possibility of evil as an attitude of will, and the presence of evil in the world and in human society is inevitable. On the other hand, because the outcome of evil appears as physical and mental “pain”, the human’s attitude toward pain, which attempts to deny suffering, induces a moral will to overcome this evil. The moral anguish, which is the “internal suffering” that we have in front of the presence of evil, makes us conscious of becoming a “moral being”, and people become self-satisfied here. Although painful, self-satisfaction and happiness about becoming a moral being is the only occasion and motive for man to overcome this by opposing the presence of evil. In other words, Lavelle’s thoughts for good and evil are based on “moral psychologism”, and the “coherence of psychological horizons and ethical horizons” between rejection of suffering and moral agony enables “ethical optimism” that man constantly overcomes evil and produces good. This is clearly an advanced modern application of scholasticism on the concept of evil.

‘진리인식을 위한 원리’로서의 시몬느 베이유의 ‘사랑의 개념’에 관한 고찰

이명곤(Lee, Myung-gon) 대한철학회 2022 哲學硏究 Vol.162 No.-

시몬느 베이유에게 있어서 사랑(l’amour)의 개념은 윤리・도덕적 행위 이전에 ‘인식의 원리’ 혹은 ‘진리인식의 원리’처럼 고려되고 있다. 이러한 사실은 그녀가 사랑의 삶으로 불림 받은 신비가로서의 삶과 무관하지 않다. 사랑이 인식의 원리인 것은 실재를 최상으로 인식하게 되는 사태가 대상에 대한 사랑을 통해서 가능하기 때문이다. 진정한 실재(réalité)에 대한 인식이란 ‘최고의 주의집중’을 통해 ‘실재와의 직접적인 접촉’을 의미하는 것이기에 이를 가능하게 하는 것이 곧 사랑의 힘이다. 따라서 사랑은 실재를 밝혀주는 빛처럼 고려된다. 사랑은 항상 사랑하는 대상의 선과 올바름을 지향하는 것이기에 윤리・도덕적 지평에서 역시 진리추구의 원리가 된다. 따라서 사랑이 없이는 진리에 대한 추구가 불가능하고, 진리에 대한 추구가 없다면 사랑은 공허하게 된다. 그리고 보다 진리에 가까이 갈수록 사랑은 보다 참되고 순수한 사랑이 된다. 이렇게 진리와 사랑은 비례적인 관계에 있다. 이러한 베이유의 사유는 탐구 대상에 대한 사랑이 부재하는 현대의 과학기술에 대한 비판적 사유를 견지하게 하며, 항상 보다 더 세계의 근원적인 존재, 신성한 존재에 가까이 다가가도록 하는 신비주의적 사랑을 추구하게 한다. For Simone Weil, the concept of love (l’amour) is considered as a ‘principle of knowledge’ or ‘principle of truth recognition’ before ethical and moral action. This fact has to do with her life as a mystic, in which she called her life of love. Love is the principle of cognition because it is through love for the object that reality is best known. Recognition of réalité means ‘direct contact with reality’ through ‘highest concentration of attention’, so it is the power of love that makes this possible. Thus, love is considered as a light that illuminates reality. Since love always aims for the good and rightness of the object it loves, it also becomes the principle of the pursuit of truth in the ethical and moral horizons. Therefore, without love, the pursuit of truth is impossible, and without the pursuit of truth, love is empty. And the closer one gets to the truth, the more true and pure love becomes. In this way, truth and love exist in a proportional relationship. Such philosophy keeps the critical thinking about modern science and technology in the absence of love for the subject of inquiry, and pursues mystical love that brings us closer to the divine existence, the fundamental existence of the world.
