Such movements appear at first as a multiplicity, and are most directly effective through that which is distinctive in the particular departments of life. But through all multiplicity and above it, there is a striving towards a comprehensive unity; every advance towards this unity is an immediate gain in stability and certainty. Nothing helps the individual to become inwardly firm more than the unification of his life in a whole of activity, more than becoming certain of an inward all-comprehensive task in the development of a spiritual individuality. The development of a spiritual individuality is a task that comes to him from within, and which, while it is more than anything else his own, is yet above all caprice. This task may tend little to promote that which is usually called happiness; the striving to fulfil it may transform the whole of existence into a state of toil and trouble, of conflict and care; and yet it alone gives to life a meaning and a value, a sure direction and a secure self-consciousness, and by assuring man of a spiritual existence of his own makes him certain of the spiritual life as a whole. Such a unification of the manifold activities so as to form a life-work, an incomparable kind of spiritual being, is something entirely axiomatic, which is in no way derived from outside. Again, this unification does not depend upon particular representations of the world; only the fanaticism of party can bind it to definite doctrines of the human and the divine. It itself, however, is a secure starting-point for the development of convictions; its acknowledgment involves the acknowledgment of a spiritual world independent of and operative within us, and summoning us to co-operation, even though this implication is often concealed from consciousness. Where our own life lacks such a fountain-head the conviction of a spiritual life never attains to axiomatic certainty, but depends on the thin threads of reasons and proofs, and therefore is most easy to overthrow. And so, for the overcoming of doubt and faintheartedness everything depends upon attaining to a unity of activity and creation which inwardly embraces life as a whole, and with this, upon being something, not simply doing something.
