The 66-year-old musician insists fans of the legendary rock band - who haven't released a studio album since 2012's 'Monster' - would ''tolerate'' new music, but what they really want to hear is the group's classic songs on their upcoming 'End of the Road World Tour'.
When asked about the possibility of new material, he said: ''I don't think so. Look, it's a different time now. I could write 'Let It Be', and people would still say, 'That's great. Now play 'Detroit Rock City'.' And I understand it, because when songs have a history with you, they're kind of like a snapshot of a time in your life, and that's not something that anything can take the place of overnight.
''It's always interesting that people say, 'When are you gonna churn out new material?' But when those acts, or any classic act turns out new material, people tolerate it.
''They're asking you to do it and they're asking you to produce it, but at the same time, they really don't want it.
''So, at some point, I go, 'Really, what's the point?' Unless it's something that's fulfilling for me, to go back in the studio just to record new KISS material, I think everything we've done so far speaks volumes and it's enough of a legacy.''
While Paul - who makes up the band alongside Gene Simmons, Tommy Thayer and Eric Singer - believes some of the group's earlier tracks are better than some of the songs which have made them famous, he ''understands'' the connection fans have to their classic tunes.
Speaking to radio host Miles ''The Shoe'' Schuman at the Rock 'N' Roll Fantasy Camp, he added: ''It's interesting that I think 'Modern Day Delilah' or 'Hell Or Hallelujah' are as good as anything we did [on the earlier albums], but I understand that people are more connected to those old classic songs.
''I understand it.''
KISS announced in September they are to bow out of performing following a 45-year career.
In a statement on their website, they wrote: ''All that we have built and all that we have conquered over the past four decades could never have happened without the millions of people worldwide who've filled clubs, arenas and stadiums over those years.
''This will be the ultimate celebration for those who've seen us and a last chance for those who haven't.
''KISS Army, we're saying goodbye on our final tour with our biggest show yet and we'll go out the same way we came in... Unapologetic and Unstoppable. (sic)''
