We try to teach valuable things in education. However, education sometimes brings negative results. Why is it so? I distinguish 'the explicit content of education' from 'the underlying content of education', arguing that we have to analyze the underlying content of education, and restructure educational content for better education. As an example I explain the case of 'epistemology of objectivism'. As a vision of education I suggest 'education for life': education for respecting life, finding and forming self-identity, restoring or reviving life, and sustaining or developing life. We are dreaming of education for truly good life. In order to realize it, we have to continuously think about what is a truly good life, what should be taught, and how we can produce it.
