$ man apt-get | grep reinsta -A2
--reinstall
Re-Install packages that are already installed and at the newest
version. Configuration Item: APT::Get::ReInstall.
So, to use it to reinstall aptitude use:
sudo apt-get install --reinstall aptitude

You can reinstall a package with sudo apt-get install --reinstall packagename.
This completely removes the package (but not the packages that depend on it), then reinstalls the package.
This can be convenient when the package has many reverse dependencies.

Sometimes you need to restore config files too! not just reinstall.
sudo apt-get install --reinstall xxxx
Reinstall the application, keeps the config files.
This could be helpful, but sometimes you need to start fresh, so what I use is this:
sudo dpkg -r xxxx //to remove that xxxx package
sudo dpkg -P xxxx //to purge all related files
then
sudo apt-get install xxxx

You should be safe to remove aptitude and reinstall, as that won't affect the other apt utilities. So: apt-get remove aptitude followed by apt-get install aptitude, or if that still fails try apt-get purge aptitude followed by apt-get install aptitude.
Before doing either of the above, I recommend a full file-system and bad-block check in case there is a problem there that caused the problem (depending on the problem, if there is one, further activity could make things worse). Also, make sure you review what will be removed in the remove/purge step before letting it proceed (it should pause to ask for permission if anything extra is changed as a result of removing that one package), to double check my thought that this is safe.
