From reading Berlinski's books and articles, I would assume that he is just unaware.
Crick would later observe that “an honest man, armed with all the knowledge available to us now, could only state that, in some sense, the origin of life appears at the moment to be almost a miracle.”
http://www.accessexcellence.org/AE/AEC/CC/crick.html--Narrator: Perhaps more than anything else Dr. Francis Crick was, and continues to be, a creative thinker and adept communicator of ideas. In his book, Life Itself: Its Origin and Nature, Crick propounds the theory of directed panspermia that he and colleague Leslie Orgel developed to explain the origin of life on earth. This notion that life on earth was seeded by microorganisms from a higher civilization and sent through space on unmanned rockets remains outside the mainstream of science; however, the mental exercises that Crick entertains both for and against his theory are stimulating and informative.
