Robert Ettinger has once again posted a message on the sci.cryonics
newsgroup which is completely "out-of-place" since it relates to
discussions which have by now proceeded quite far on the CryoNet email
list. Since there are many current readers of sci.cryonics (or future
readers of its archives) who will not have read the background to this
message, it is improper (really unethical, IMO) to make such a posting
without in addition, at least reproducing all the prior discussion.
Without that discussion (in which I played a major role, BTW), readers
are ill equipped to judge whether his statements about what has lead to
his posting are truth or fiction.

I therefore urge all readers of sci.cryonics to censure him for his
behavior (not strongly, since he is a relative newcomer to the
newsgroups and probably has little knowledge of  netiquette - not to
mention that he is suffering from a major disabilities by posting
through AOL which does not allow crossposting).

Robert Ettinger is once again obfuscating reality and distorting the
English language by trying to equate "scientific", "evidence" and even
"rational". No one said (on Cryonet) that cryonics was not
"unscientific"! but only that it did not have scientific "evidence" for
it. As I have explained (on Cryonet) these two are quite different.
Naturally, even in the experimental sciences, scientists use theory,
rationality and prior proven science, to decide what experiments should
be done, however, they do not consider this thinking and decision making
"evidence". That is quite proper mainly because it is the technical
scientific *meaning* of the word "evidence". Robert Ettinger either does
not understand that or simply will not accept it. Just as he and others
have *distorted* the meaning of "suspended animation", he now wishes to
distort the meaning of "evidence".

Here Robert Ettinger is beginning to sound exactly like those who argue
for colloidal mineral, aromatherapy, homeopathy, or any other as yet
unproved alternative medical approach to curing diseases. For someone
who purports to be so "scientific" and in favor of a "scientific
approach", his argument sounds suspiciously similar to so many who are
anti-science and technology, and even back-to-nature luddites.

To the establishment all theories which are practiced without evidence
for their success, are quite properly termed "quackery". To them, the
alternative medicine ideas stated above, and most life extension ideas
*are* "cryonics-like" in this sense and to the extent to which they are
practiced are quackery. The only valid reasons we have for objecting to
this are what I have previously elucidated (on CryoNet) and some others
(on CryoNet) have agreed with.

I certainly do.

But there is no "scientific evidence" until at least a working prototype
is made.

You are confusing many things: efficacy, safety, salability, etc. These
are all completely different aspects of what is needed for "success",
which is quite unrelated to scientific truth or technological
accomplishability.

The word "scientific" simply has no application to that context.

It is always advantageous to tell what you believe to be the truth.

Again, you are confusing words. *One* positive experimental result is
evidence. For proof it takes a *lot* of positive experimental results
under many circumstances, by many different investigators, with
controls, etc. even double blinded if possible. Revolutionary ideas
which will change paradigms of thought require (quite properly again) an
enormous amount of such "evidence" before their *proof* is acceptable.

At the beginning of this post you hurled out the word "absurd".
Now, I will throw it back to you. 
IMO, any attempt to compute the probability of any current patient's
restoration is "scientifically" absurd!
It may have some "rational" and "logical" components to it, but it is
still "scientifically" absurd.

Readers of your posts here respect you as the father of cryonics, but
scientists elsewhere will simply laugh at those calculations and be even
more convinced than ever that cryonicists are "quacks"
