That belief in liberty led Ken to the Cato Institute. In his later years, he became close with Cato scholars like Roger Pilon, whose work on constitutional studies mirrored his own convictions.
Beginning in 1989, Cato advanced a unique philosophy: Judges should be neither active nor restrained but instead responsible to the Constitution they swear to uphold. This philosophy deeply resonated with Ken, inspiring him to champion the broader adoption of judicial engagement in protecting liberty.
