Sydney Turner Klein (1853-1934) was the British author of: Science and the Infinite; or, Through a Window in the Blank Wall (1912), From the Watch Tower (1917) and The Way of Attainment (1924). "The proof that the Human Race is still in its infancy may be seen in the fact that we still require Symbolism to help us to maintain and carry forward abstract thought to higher levels, even as children require picture books for that purpose. The Glamour of Symbolism, Rapture of Music, and Ideal of Art, which come to us in later years, had their beginnings when to the child every blade of grass was a fairy tale and a grass plot a marvellous fairy forest. The great aspiration of the Human Race is to gain a knowledge of the Reality, the Noumenon behind the phenomenon; but the fact that from infancy we have been accustomed to confine our attention wholly to the objective, believing that to be the reality, has surrounded us with a concrete boundary wall through which we can only at times, with difficulty, get transient glimpses of that which is beyond.
