Invisible Man promotes a political philosophy of appealing to the emotional individual. It rejects all forms of ideology, arguing that ideology misses the trees for the forest, so to speak (in other words, the idea that ideology focuses too much on the collective at the expense of the individual). Several forms of black politics are depicted in the novel, including conservative progress, black nationalism, and communism.
The narrator cares more for individuals than the Brotherhood, and that is the irreconcilable disagreement between them.
