There appears to be an irresolvable disagreement between "progressives" and "conservatives" regarding the ultimate aims of education. This paper argues that the dispute is irresolvable as it currently stands because the traditional progressive/conservative dichotomies are false and based on distorted half-truths. The current impasse is due to the fact that educationalists and philosophers alike have hitherto misunderstood the fundamental purpose of educational activities. The central claim of this paper is that a "biological" perspective on education allows one to see past the traditional dichotomies and affords a coherent rationale for a set of curricular priorities by providing the framework necessary to draw principled distinctions between education, training, indoctrination, and enculturation, all without having to draw on contentious politico-ideological commitments.
