Abstract
The Abolition of Man
, though short in length and casual in tone, is among the most important books of the twentieth century. The reason it possesses such significance is that it reveals through penetrating analysis the contemporary sceptical assault on the very possibility of rational morality and, indeed, on the very meaning of human life. In meeting and overcoming this assault, Lewis embraces the concept of objective value. But this concept is itself under attack in modernity, most notably in Nietzsche's
Beyond Good and Evil
. There is, however, an effective response to this withering onslaught. It is found in Michael Polanyi's ‘fiduciary’ philosophy. This study shows how Polanyi's account of justification inoculates Lewis' objective value against Nietzsche's virulent attack, thereby preserving the defence of meaning and morality that constitutes the essential contribution of
The Abolition of Man
.
