但丁的《神曲》作为中世纪向文艺复兴时期转型的代表性作品，在表现基督教背景下的人文主义思想上有着典型性。论文试图通过分析作品中对基督教“三位一体”在结构上的投射和在表现人的“理性”与“自由意志”上的倾向，以及对于《地狱》第七圈中自杀者变树情节的思考，来论证但丁在那个特殊的思想转变时期作出的现世思考。

Since ancient Greece, The Divine Comedy has been undoubtedly one of the most Christian humanist works. The main reason is because Dante was a devout believer. He accepted the ontology of Christian theology, and the entire the Divine Comedy shows that God is the "source of all things" and the "supreme ruler" of the universe. But under the shroud of these powerful gods, Dante showed a strong concern for the world in his texts, and he had a strong humanistic tendency. This kind of humanistic thought is not only reflected in the time-space structure that pays tribute to the Christian doctrine of the "Trinity", but also in the shaping of the characters. As an Italian national poet at the end of the Middle Ages, Dante was able to find the "new ideas" of humanism within the framework of Christianity, which was not only his own genius creation, but also the inevitable development of history.
