These rooms are described as a perfect palace of confusion--chaos on chaos heaped of chemical apparatus, books, electrical machines, unfinished manuscripts, and furniture worn into holes by acids. It was perilous to use the poet's drinking-vessels, less perchance a seven-shilling piece half dissolved in aqua regia should lurk at the bottom of the bowl. Handsome razors were used to cut the lids of wooden boxes, and valuable books served to support lamps or crucibles; for in his vehement precipitation Shelley always laid violent hands on what he found convenient to the purpose of the moment. Here the friends talked and read until late in the night. Their chief studies at this time were in Locke and Hume and the French essayists. Shelley's bias toward metaphysical speculation was beginning to assert itself. He read the School Logic with avidity, and practised himself without intermission in dialectical discussion. Hogg observes, what is confirmed by other testimony, that in reasoning Shelley never lost sight of the essential bearings of the topic in dispute, never condescended to personal or captious arguments, and was Socratically bent on following the dialogue wherever it might lead, without regard for consequences. Plato was another of their favourite authors; but Hogg expressly tells us that they only approached the divine philosopher through the medium of translations. It was not until a later period that Shelley studied his dialogues in the original: but the substance of them, seen through Mdme. Dacier's version, acted powerfully on the poet's sympathetic intellect. In fact, although at the time he had adopted the conclusions of materialism, he was at heart all through his life an idealist. Therefore the mixture of the poet and the sage in Plato fascinated him. The doctrine of anamnesis, which offers so strange a vista to speculative reverie, by its suggestion of an earlier existence in which our knowledge was acquired, took a strong hold upon his imagination; he would stop in the streets to gaze wistfully at babies, wondering whether their newly imprisoned souls were not replete with the wisdom stored up in a previous life.
