This peculiarity of the Semitic and Aryan languages must have had the greatest influence on the formation of their religious phraseology. The Semitic man would call on God in adjectives only, or in words which always conveyed a predicative meaning. Every one of his words was more or less predicative, and he was therefore restricted in his choice to such words as expressed some one or other of the abstract qualities of the Deity. The Aryan man was less fettered in his choice. Let us take an instance. Being startled by the sound of thunder, he would at first express his impression by the single phrase, It thunders,--βρουτᾶ. Here the idea of God is understood rather than expressed, very much in the same manner as the Semitic proper names Zabd (present), Abd (servant), Aus (present), are habitually used for Zabd-allah, Abd-allah, Aus-allah,--the servant of God, the gift of God. It would be more in accordance with the feelings and thoughts of those who first used these so-called impersonal verbs to translate them by He thunders, He rains, He snows. Afterwards, instead of the simple impersonal verb He thunders, another expression naturally suggested itself. The thunder came from the sky, the sky was frequently called Dyaus (the bright one), in Greek Ζεὑς; and though it was not the bright sky which thundered, but the dark, yet Dyaus had already ceased to be an expressive predicate, it had become a traditional name, and hence there was nothing to prevent an Aryan man from saying Dyaus, or the sky thunders, in Greek Ζεὑς βρουτᾶ. Let us here mark the almost irresistible influence of language on the mind. The word Dyaus, which at first meant bright, had lost its radical meaning, and now meant simply sky. It then entered into a new stage. The idea which had first been expressed by the pronoun or the termination of the third person, He thunders, was taken up into the word Dyaus, or sky. He thunders, and Dyaus thunders, became synonymous expressions, and by the mere habit of speech He became Dyaus, and Dyaus became He. Henceforth Dyaus remained as an appellative of that unseen though ever present Power, which had revealed its existence to man from the beginning, but which remained without a name long after every beast of the field and every fowl of the air had been named by Adam.
