Frank Auerbach on the importance of language (?)

I could have sworn that, during the recent (rare) interview with Frank Auerbach, there was a passage in which – in the context of the current migration crisis – Auerbach stressed the importance of language (for integration etc.), but I can't find it now. Something along the lines of "language is more important than looks", I think, unless I'm imagining it?
