To this pilgrimage the diffident are foreordained; it is their happiest hour when they take staff and scrip and set out in earnest for the shrine built among the mountains. The gardens of Armida are not for them, nor the warm breezes fragrant of fruit and flowers; but the vision of a far peak flushed at sundawn draws them onward, and strength and peace are increased upon them throughout the great ascent. He is still too rich for pity to whom renunciation brings these high and enviable hours. But the heavens are not opened every day, and the adept of these mysteries must walk the dull round of common life like other men, not warmed as they are by the glow of constant friendship, yet cheered by intermittent flames of remembrance and of hope. The real life of the diffident is cunningly hidden from those around them, for whom, indeed, it is wont to have faint interest; but before you who have often sought me out through fair and foul weather, I may venture to undo the pack of small resources which brings variety and distraction into lonely days. Firstly, I still dare to haunt the forecourts of philosophy. Into her inner courts I may not penetrate, lacking the leisure which her whole service demands; yet the loiterings which I may still enjoy are to me like voyages into a foreign country, and give my mind the healthful enjoyment of change; they are not long enough to bring that whole detachment from daily life which, in my case, might prove a perilous advantage. All that I need for common use is a simple rule based on a few fundamental thoughts to give me a course upon the wayward ocean, and though it be full of error as the Almagest, yet it shall surpass the thumb-rules of Philistia. It must be a doctrine which allows imagination her right and durable career, and therefore not be monist. For materialism is too wildly imaginative at the start: like a runner who at the outset overstrains his heart and thereafter runs no more, the follower of this creed, by his postulate of a blind impersonal Law, exhausts his power of speed and plods henceforth eyes downward over flattest plains of dulness. That my mind may remain curious and alert in isolation, I must conceive in the universal scheme a power that does not alone impel, but also draws me forward. For were it true that the sum of things blunders from change to change, swept by blind force into uncharted voids, I should abandon myself in despair to that hopeless course, and drift indifferent to the direction or the end.
