We give a purely category-theoretic proof of the result of Makkai and Paré saying that the category Lin of linearly ordered sets and order preserving injective mappings is a minimal finitely accessible category. We also discuss the existence of a minimal ℵ_1-accessible category.
Keywords: accessible category, indiscernibles, linear order
