 In the remainder of this entry we will frame questions from the perspective of the mental representation view, but readers who prefer a different view can reframe the issues in their preferred terms.  For example, the questions “Can there be concepts without language?” is typically understood on the mental representation view as asking whether a pre-linguistic or non-linguistic agent can entertain mental representations of a particular kind.  If one adopts the view that concepts are abstract objects, the corresponding question might be whether a pre-linguistic or non-linguistic agent can stand in the concept possession relation to concepts understood as abstract objects of a certain type.  And if one adopts the view that concepts are abilities, the corresponding question might be whether a pre-linguistic or non-linguistic agent can have the abilities that are constitutive of concept possession.
