Given the fact that the completeness of Jaspers’s idea of ‘world philosophy’ was hindered by his departure from life, this paper aims to speculate about the possible further directions of this peculiar philosophical concept of his. In particular, by taking into account the general principles of Jaspers’s philosophy, as well as the spiritual situation of our age, the paper makes a tripartite emphasis on man’s existential self- creation in the world through which philosophy receives its genuine content and, by such a ‘truthing’ of philosophy, a possible instruction for its future, going beyond all the attempts of its present and hopeless surrogates. Being fully personally immersed in his philosophy, Jaspers offered a clear demonstration of the true meaning of inseparability of the philosophical opus and the person behind it. From this position, the paper also reflects on the basic question of how to understand an idea that cannot be thought of unless it is something we live by.
