Contemplation at its commencement is commonly and indiscriminate- ly applicable; but continuately, or subsequently, it assumes an obsequiousness to more distinguishing investigation. The converse of the antecedent pro- position is apparently and occasionally remarkable; to this determination the experience of most dis- criminating individuals will bear probable testimo- ny. Another consideration constantly alive to the apprehension of the philosopher, is, the remembrance of this circumstance, that the human mind can con- template, intelhgibly and distinctly, only one object at the same moment, with the anticipation of satis- factory discrimination and ascertainment. H. The mind, ever active and expansive, abhors the notion of confinement, and rests not upon inde- termined generality, but institutes, until perfect discovery be obtained, the supporting intermedium of probability, which is frequently unsteady and deceitful; but by perseverance, after sojourning through a wilderness of cloudiness and perplexity, tlie truth is conclusively attainable. Having, there- fore, reviewed objects both collectively, or aggre- gately, and singularly, or disjointly, it condescends to the comparison of individuals and the advantages of the consequences.
