Dyson suggested that philosophers can be broadly, if simplistically, divided into lumpers and splitters. While lumpers consistently tried to create coherent patterns, splitters preferred incoherent complexity. J H Hexter characterized such historians as "lumpers". Lumpers and splitters may propose as many as eight species or as few as one. Lumpers provided inexpensive food to feed the Irish masses. According to him, "lumpers" rejected differences and chose to emphasize similarities. Lumpers objected to goods being unloaded by non-union labour from the ship "Dimboola".
