Thus we have finished our examination of the several systems of philosophy, both of the intellectual and moral world; and, in our miscellaneous way of reasoning, have been led into several topics, which will either illustrate and confirm some preceding part of this discourse, or prepare the way for our following opinions. 'Tis now time to return to a more close examination of our subject, and to proceed in the accurate anatomy of human nature, having fully explained the nature of our judgment and understanding. [16] If the reader is desirous to see how a great genius may be influenced by these seemingly trivial principles of the imagination, as well as the mere vulgar, let him read my Lord Shaftsbury's reasonings concerning the uniting principle of the universe, and the identity of plants and animals. See his _Moralists_, or _Philosophical Rhapsody_. SECTION VII. CONCLUSION OF THIS BOOK. But before I launch out into those immense depths of philosophy which lie before me, I find myself inclined to stop a moment in my present station, and to ponder that voyage which I have undertaken, and which undoubtedly requires the utmost art and industry to be brought to a happy conclusion. Methinks I am like a man, who, having struck on many shoals, and having narrowly escaped shipwreck in passing a small frith, has yet the temerity to put out to sea in the same leaky weather-beaten vessel, and even carries his ambition so far as to think of compassing the globe under these disadvantageous circumstances. My memory of past errors and perplexities makes me diffident for the future. The wretched condition, weakness, and disorder of the faculties, I must employ in my inquiries, increase my apprehensions. And the impossibility of amending or correcting these faculties, reduces me almost to despair, and makes me resolve to perish on the barren rock, on which I am at present, rather than venture myself upon that boundless ocean which runs out into immensity. This sudden view of my danger strikes me with melancholy; and, as 'tis usual for that passion, above all others, to indulge itself, I cannot forbear feeding my despair with all those desponding reflections which the present subject furnishes me with in such abundance.
