The powers, and faculties, and principles that are necessary fully to comprehend all that we see and all that surrounds us, exist and have been bestowed on man by his beneficent Creator. Still, it is only by slow degrees that he is to become their master, acquiring knowledge, step by step, as he has need of its services, and learns how to use it. Such seems to be the design of Providence, which is gradually opening to our inquiries the arcana of nature, in order that we may convert their possession into such uses as will advance its own wise intentions. Happy are they who feel this truth in their character of individuals! Thrice happy the nations which can be made to understand, that the surest progress is that which is made on the clearest principles, and with the greatest caution! The notion of setting up anything new in morals, is as fallacious in theory as it will be found to be dangerous in practice.
