Prof. Barcan Marcus has convincingly shown that belief formation is independent
from language possession. This view has now gained a wide currency among philosophers
of mind. Many philosophers, however, are presently claiming that linguistic expression
is required to form higher-order beliefs. This is supposed to apply to metacognition
– the kind of mental activity through which one is trying to predict and evaluate one's
own mental dispositions, states and properties for their cognitive adequacy. Arguments
will be offered to show that metacognition does not need to refer to conceptual
representations of attitudes, and does not require language possession.
