		<description>&lt;blockquote&gt;
You can develop incredible insight into how those symbols behave, but you’re not doing geometry.
&lt;/blockquote&gt;
But isn't that what's precisely nice about mathematics that I don't have to develop the intuition to do geometry, physics, etc. ? Intuition is certainly good to have and I wish I had it for all kinds of subjects, but there's no methodical way to develop it.</description>

		<description>You are correct, Sigfpe, that algebra allows geometry to be done by people without geometric intuition.  But what is the nature of this intuition?  I doubt anyone had or has any *inherent* intuition for non-Euclidean geometry, since our entire every-day experience as children is Euclidean. Physicists only started to think that the Universe may be better modeled with a non-Euclidean geometry after such geometries had been developed by those clever algebraists, Gauss, Bolyai and Riemann.  Some other clever people --eg, Frege -- simply could not accept that non-Euclidean geometry was more than abstract nonsense, unconnected to anything in the real world.</description>

		<description>Instead of learning to solve the problem algebra allows you instead to manipulate symbols. The Devil's minion, Descartes, allowed people with no geometrical insight to start proving theorems about geometry. You can develop incredible insight into how those symbols behave, but you're not doing geometry. Even worse, people can be so far removed that they even fail to realise that they are doing geometry.</description>

		<description>Ford: I wondered the same thing about algebra being the devil, which probably demonstrates that we're both irretrievably damned.</description>

		<description>How is topology/category theory winning?

Why is Abstract Algebra cast as "the devil"?</description>
