Why is the quote environment defined as a list?

In the standard LaTeX classes the quote and quotation environments are defined as lists. Is there a particular reason for this? After all they do not look like lists!

So, the generic LaTeX command which starts an indented environment is \list. \quote is such an environment even if there are not several items but just one. Thus it uses \list.
The name \list might unfortunately be a bit misleading.
