worlds, whose invisibility adds only to the sublimity of the speculation.

Lastly, I have shown that all which Providence has placed within our`grasp, is the sights, tastes, feels, sounds, and smells that our senses reveal to us; that we cannot even ask a significant question unless it refers to these, and every answer is insignificant that has not a similar reference.

What I have to say further concerning the Philosophy of Human Knowledge, may with propriety constitute a separate division: but before I adventure on it, I would fain know whether I can excite interest or convey information. I am too well aware of the insidiousness of selflove, to be satisfied with my own suggestions, and to painfully conscious of the depression of timidity, to retract without an effort. What I have advanced is not the fugitive offspring of a sudden intention, but the slow and painful product of contemplative years. If I have wholly mistaken my abilities, it is time I was undeceived. To the public, then, I confide the question; and though I have no reason to expect a favourable decision, a failure will at least save me from perseverance in a fruitless undertaking.
