Most of the works of art are esteemed beautiful, in proportion to their fitness for the use of man, and even many of the productions of nature derive their beauty from that source. For as it was found that mathematical conclusions all proceed according to the principle of contradiction (which the nature of every apodeictic certainty requires), people became persuaded that the fundamental principles of the science also were recognized and admitted in the same way. Causality according to the laws of nature, is not the only causality operating to originate the phenomena of the world. Secondly, The same course of reasoning will make us conclude, that there is but one kind of necessity, as there is but one kind of cause, and that the common distinction betwixt moral and physical necessity is without any foundation in nature. For the notion of injury or injustice implies an immorality or vice committed against some other person: And as every immorality is derived from some defect or unsoundness of the passions, and as this defect must be judged of, in a great measure, from the ordinary course of nature in the constitution of the mind; it will be easy to know, whether we be guilty of any immorality, with regard to others, by considering the natural, and usual force of those several affections, which are directed towards them. By observation and analysis of phenomena we penetrate into the interior of nature, and no one can say what progress this knowledge may make in time. Or if they esteem that opinion absurd and impious, as it really is, I shall tell them how they may avoid it; and that is, by concluding from the very first, that they have no adequate idea of power or efficacy in any object; since neither in body nor spirit, neither in superior nor inferior natures, are they able to discover one single instance of it.
