You are certainly right in insisting on the strong metaphysical needs of mankind; but religion appears to me to be not so much a satisfaction as an abuse of those needs. At any rate we have seen that in regard to the furtherance of morality, its utility is, for the most part, problematical, its disadvantages, and especially the atrocities which have followed in its train, are patent to the light of day.

[So hast du gewiß Recht, das starke metaphysische Bedürfniß des Menschen zu urgiren: aber die Religionen scheinen mir nicht sowohl die Befriedigung, als der Mißbrauch desselben zu seyn. Wenigstens haben wir gesehn, daß in Hinsicht auf Beförderung der Moralität ihr Nutzen großentheils problematisch ist, ihre Nachtheile hingegen und zumal die Gräuelthaten, welche in ihrem Gefolge sich eingestellt haben, am Tage liegen.]

Arthur Schopenhauer (1788-1860) German philosopher

You are certainly right in advocating the strong metaphysical needs of mankind; but religions appear to me to be not so much a satisfaction as an abuse of those needs. At any rate we have seen that, in view of the progress of morality, its advantages are for the most part problematical, while its disadvantages, and especially the enormities which have appeared in its train, are obvious.
[tr. Dircks]

You are certainly right in insisting on man's strong metaphysical need. Religions, however, seem to me to be not so much a satisfaction but an abuse thereof. at any rate, we have seen that, as regards the encouragement of morality, their use is to a great extent problematical, whereas their disadvantages, and especially the atrocities that have followed in their train, are as clear as the light of day.
