The condition of what is called the scientific mind in England to-day may be described as chaotic. Its researches begin nowhere and end nowhere. Its representative men deny the facts of consciousness, or misinterpret them, which is equivalent to negation, and thus ignore the subjective starting point of all knowledge, while they relegate God to the domain of the unknowable, thereby removing from sight the true end and goal of all inquiry. Nothing, then, is the Alpha and Omega of their systems, and it is small matter of surprise that theirs has been called the philosophy of nihilism. Yet it is sadly true that the votaries of scientism (_salvâ dignitate, O scientia!_) are on the increase, and that Huxley, Spencer, Darwin, and Tyndall usurp among the fashionable leaders of thought, or rather the leaders of fashionable scientific thought, to-day, the place lately held by Mill, Renan, Strauss, and Hegel. It is not quite the _ton_ now to content one’s self with denying the divine inspiration of Holy Writ or with questioning the Divinity of Christ. We must iterate our belief that in matter are to be found the “promise and potency of every form and quality of life,” or that all living things sprang from a primordial homogeneous cell developed in a primitive plastic fluid eruditely denominated “protoplasm”; nay, we must join hands with Herbert Spencer, and affirm of the First Cause that it is unknowable and entirely divested of personal attributes. It is evident that scientism is more rigorously sceptical than rationalism or the materialism of the eighteenth century――in a word, that it is supremely nihilistic. Being such, it is worth while to inquire through what influence it has succeeded in dominating over so many vigorous minds, and winning to its standard the rank and file of non-Catholic scholars. It presents to the expectant lover of truth a set of interesting facts which fascinate as well by their novelty and truth as by the hope that the “open sesame” which unearthed them cannot but swell the list, and that whatever it pronounces upon is irrevocably fixed. No one can gainsay the value to science of the brilliant experiments and interesting discoveries of Prof. Tyndall, nor underrate the painstaking solicitude of Darwin. Indeed, we are all more or less under the thraldom of the senses, and the truths which reach our minds through that channel come home with irresistible force. Hence the allurements of science for the majority of men, and their complete subjection to the authority of scientific discoverers. No wonder, therefore, that when a slur is cast upon the supersensible order――that order with which they have neither sympathy nor acquaintance――that same majority are ready to deride the sublimest truths of Christianity, and to devour the veriest inanities as the utterances of sound philosophy. No wonder that, captivated by the fast-increasing array of fresh discoveries in the field of
