by the way this is the way the debate should be had.... the author mentions the critiques right up front on page 3-4... and some he admits are potential stumbling blocks...
here is a sample...
"In this paper I shall examine a particular variant of the fourth view, that the
fraction of baryons that develops into living organisms is maximized by the observed
constants of physics. This hypothesis is in principle falsiï¬able, and I shall argue
that considerations of hypothetical variations of the cosmological constant give a
very preliminary inconclusive hint that it may become falsiï¬ed, since the fraction
of baryons that condense into galaxies that in turn form living organisms would be
higher if the cosmological constant were lower. This result thus gives a preliminary
suggestion that there might eventually be evidence against optimal ï¬ne tuning for
3life (or at least for maximizing the fraction of baryons that become living organisms)
by such a biophilic principle.
However, email comments by Robert Mann [11], Michael Salem [12], and Martin
Rees [13] have shown me that it is not at all clear that the very small increase in the
fraction of baryons that would condense into galaxies if the cosmological constant
were zero instead of its tiny observed positive value would also lead to an increase in
the fraction of baryons that would go into life, since conceivably the small diï¬erences
in the galaxies produced by lowering the cosmological constant to zero might also
aï¬ect the fraction of baryons within galaxies that become life in a way that would
overcompensate for the higher fraction of baryons condensing into galaxies."

.....or have you finally gone completely total, talking in the third person.
