I wonder because his latest (new but posthumously published) article, ends plainly:
Tzitzit, with their thread of blue, remind us of heaven, and that is what we most need if we are consistently to act in accordance with the better angels of our nature.
No added jawing about how we no longer have this blue thread, etc., etc.
P.S., I see BlueFringes.com answers our question in the positive, but I cannot access the page.
