We have just been favoured with a pamphlet from Mr Bailey, entitled "A Letter to a Philosopher, in Reply to some Recent Attempts to Vindicate Berkeley's Theory of Vision, and in further Elucidation of its Unsoundness." Our article on Mr Bailey's review of Berkeley's theory, which appeared in _Blackwood's Magazine_ of June 1842, was one of these attempts. Had the author merely attacked or controverted our animadversions on his book, we should probably have left the question to its fate, and not have reverted to a subject, the discussion of which, even in the first instance, may have been deemed out of place in a journal not expressly philosophical. There is, in general, little to be gained by protracting such controversies. But, as Mr Bailey accuses us, in the present instance, of having misrepresented his views, we must be allowed to exculpate ourselves from the charge of having dealt, even with unintentional unfairness, towards one whose opinions, however much we may dissent from them, are certainly entitled to high respect and a candid examination, as the convictions of an able and zealous enquirer after truth. In our strictures on Mr Bailey's work, we remarked, that he had represented Berkeley as holding that the eye is not directly and originally cognizant of the outness of objects in relation to each other, or of what we would call their reciprocal outness; in other words, we stated, that, according to Mr Bailey, Berkeley must be regarded as denying to the eye the original intuition of space, either in length, breadth, or solid depth. It was, however, only in reference to one of his arguments, and to one particular division of his subject, that we laid this representation to his charge. Throughout the other parts of his discussion, we by no means intended to say that such was the view he took of the Berkeleian theory. Nor are we aware of having made any statement to that effect. If we did, we now take the opportunity of remarking, that we restrict our allegation, as we believe we formerly restricted it, to the single argument and distinction just mentioned, and hereafter to be explained.
