A second series of writers who now appeared have mainly to do with particular attempts made in Philosophy which remained attempts merely, and are only found while this terrible time of upheaval lasted. Many individuals of that period saw themselves forsaken by what had hitherto been accepted by them as content, by the object which up to this time had formed the stay and support of their consciousness—by faith. Side by side with the peaceful reappearance of the ancient philosophy there displayed itself, on the other hand, a multitude of individuals in whom a burning desire after the conscious knowledge of what is deepest and most concrete was violently manifested. It was spoilt, however, by endless fancies, extravagances of the imagination and a craze for secret, astrological, geomantic and other knowledge. These men felt themselves dominated, as they really were, by the impulse to create existence and to derive truth from their very selves. They were men of vehement nature, of wild and restless character, of enthusiastic temperament, who could not attain to the calm of knowledge. Though it cannot be denied that there was in them a wonderful insight into what was true and great, there is no doubt on the other hand that they revelled in all manner of corruption in thought and heart as well as in their outer life. There is thus to be found in them great originality and subjective energy of spirit; at the same time the content is heterogeneous and unequal, and their confusion of mind is great. Their fate, their lives, their writings—which often fill many volumes—manifest only this restlessness of their being, this tearing asunder, the revolt of their inner being against present existence and the longing to get out of it and reach certainty. These remarkable individuals really resemble the upheavals, tremblings and eruptions of a volcano which has become worked up in its depths and has brought forth new developments, which as yet are wild and uncontrolled. The most outstanding men of this nature are Cardanus, Bruno, Vanini, Campanella, and lastly Ramus. They are representative of the character of the time in this interval of transition, and fall within the period of the Reformation. 1. CARDANUS.
