" The fundamental fault of the nihilist is that, challenging all given values, he does not find, beyond their ruin, the importance of that universal, absolute end which freedom itself is. It is possible that, even in this failure, a man may nevertheless keep his taste for an existence which he originally felt as a joy. Hoping for no justification, he will nevertheless take delight in living. He will not turn aside from things which he does not believe in. He will seek a pretext in them for a gratuitous display of activity. Such a man is what is generally called an adventurer. He throws himself into his undertakings with zest, into exploration, conquest, war, speculation, love, politics, but he does not attach himself to the end at which he aims; only to his conquest. He likes action for its own sake. He finds joy in spreading through the world a freedom which remains indifferent to its content. Whether the taste for adventure appears to be based on nihilistic despair or whether it is born directly from the experience of the happy days of childhood, it always implies that freedom is realized as an independence in regard to the serious world and that, on the other hand, the ambiguity of existence is felt not as a lack but in its positive aspect. This attitude dialectically envelops nihilism’s opposition to the serious and the opposition to nihilism by existence as such. But, of course, the concrete history of an individual does not necessarily espouse this dialectic, by virtue of the fact that his condition is wholly present to him at each moment and because his freedom before it is, at every moment, total. From the time of his adolescence a man can define himself as an adventurer. The union of an original, abundant vitality and a reflective scepticism will particularly lead to this choice. "
