Jürgen Habermas and Richard Rorty share many philosophical commitments. However,
their ways have parted when Habermas has begun to emphasize the essential or internal
connection between justification and truth, and especially with its feature which
may be described as unconditional or universal validity. Rorty strongly disagrees with
Habermas’s contention about the essential connection between justification and truth,
and puts into doubt the unconditionality claim involved in the latter notion. In this debate Habermas is arguably more convincing, but his arguments may be strengthened
by pointing out that not only we do need the notion of truth over and above the notion
of justification, but the notion of truth is also involved in the very notion of justification.
