On Tasteless People: A philistine is and remains {Greek: amousos anaer}.
By philistine, Schopenhauer means people who are always seriously occupied with realities which are no realities;
Someone without mental needs and no intellectual pleasures.
As he possesses no intellectual, but only physical need, he socialises with those who can satisfy the latter, but not the former. The last thing expected from friends is them having of any sort of intellectual capacity.
The great affliction of all philistines is that they have no interest in ideas, and that, to escape being bored, they are in constant need of realities.
