"The reason why algebra is important has nothing to do with the GP's idea that it is the most objective of studies." I said neither that algebra is important, nor that it is the most objective.

Even if algebra served no other practical or intellectual purpose at all, the fact that it reveals educational problems is valuable in and of itself. And that quality is due to its objective nature.
