Abstract
There are two types of historians: the vivid historian or butterfly and the technical historian or caterpillar. The former believes that complete history is neither possible nor desirable. Selection is necessary, and proper selection distinguishes good historians from bad ones. Facts are unimportant in themselves but are used to find underlying principles. The latter puts a premium on the discovery of new facts, letting interpretation take care of itself. While the technical historian's truths are too small, the vivid historian's truth is too big. The differences between the two types, in part temperamental, are also based on the periods in which they work; non-modern historians tend to be technical and modern historians vivid because the former are faced with a scarcity of sources, the latter with an overabundance
