What does "occasional bursts of blind" in this example mean?
Rosseau, too, must have reinforced the coarse-grained, rough peasant in Tolstoy with his strongly moralistic, puritanical strain, his suspicion of, and antipathy to the rich, the powerful, the happy as such, his streak of genuine vandalism, and occasional bursts of blind, very Russian rage against Western sophistication and refinement, and that adulation of 'virtue' and simple tastes, of the 'healthy' moral life, the militant, anti-liberal barbarism, which is one of Rousseau's specific contributions to the stock of Jacobin ideas.
I've searched that in many dictionaries and haven't found a clear answer.
Is this a phrase or expression?
