The dualism of liberal vs vocational education seems very common in educational history. The purpose of this paper is to provide an argument to resolve the dichotomy by emphasizing the profession in vocational education. As we know, there are three popular claims of general education-the Maritain's educational view in perennialism, Harvard Red Book, and the liberal education view by Hirst. Although these three claims emphasize the importance of general education, the researcher think they debase the vocational education potentially. And that results in the dualism of liberal vs vocational education. If we clarify the professional concept in vocational education and highlight vocational knowledge from different discipline and particular professional ethics, then we can establish the spirit of general education in vocational education and resolve the dualism between them.
