 It is common to dismiss objectionable features of a past thinker’s work under the excuse that “everyone is a product of their times,” and thus cannot be fairly judged for embracing views and language that were then widely accepted. The presumption is that we can excise the objectionable elements, while still carrying the main ideas forward.  On this view, we can excuse the objectionable parts as something like incidental errors, which can be corrected without affecting the substance of what was written. Such elements should be identified and placed in context but, unlike mere typographical errors, the offending material should be fully acknowledged and not merely erased.
