It was only after much hesitation that I accepted your flattering invitation to contribute to this meeting in commemoration of Aubrey Lewis. On the one hand, I have the natural diffidence of a layman amongst experts. But as against this, although we were of the same generation, I cannot but be moved by a feeling akin to filial piety towards one whose work I so greatly admired, and to whom I am indebted for so many personal acts of kindness and generosity as I have been to Aubrey Lewis. I hope, therefore, that since the latter emotion has prevailed you will think it fitting that I should ask you to look back, from the standpoint of nearly a quarter of a century later, at the impressive paper on Health as a Social Concept which Aubrey Lewis read to the British Sociological Association in 1953.
