One of the most common criticisms of cryonics is to argue that cryonics can only be a legitimate endeavor when there is (peer reviewed) demonstration of whole body suspended animation. Advocates of cryonics  point out that this is an unreasonable position because it sets a standard for rational decision making (certainty) that is rarely encountered, [...]

There has been some discussion about relatives causing suspensions to not take  place as the cryonics member gets older and how we cryonicists can protect  ourselves from this happening.
Suspension interference happens more then most cryonicists realize. As a retired member of Alcor management I have seen a lot of it.  Sometimes relatives  cause the suspension [...]

Advocates of human cryopreservation argue that death is not an event but a process. Cryonics patients are stabilized at low temperatures in anticipation of a second medical opinion in the future. This raises an important ethical issue. What is the moral status of cryonics patients? It is not possible to argue that cryonics patients will [...]

In the March 2010 issue of Reason magazine Tim Cavanaugh writes about the rift between transhumanists who favor biological enhancement versus those who favor non-biological “mechanical” enhancement:

These days transhumanists talk a lot about subcutaneous data ports, permanent immersion in virtual reality, even extending male life spans by removing the gonads. But they spend noticeably little [...]

There are various competing strategies how to achieve meaningful life extension or rejuvenation, including , but not limited to, genetic manipulation, periodical elimination of damage, caloric restriction,  molecular nanotechnology and mind uploading. A useful review of these strategies has been published in the book The Scientific Conquest of Death: Essays on Infinite Lifespans (2004) by [...]

The biology-of-aging blog Ouroboros has posted a skeptical post about cryonics that is highly representative of how most biological scientists respond to questions about cryonics. The discussion of cryonics is largely reduced to a discussion of the technical feasibility of suspended animation and resuscitation requirements. But suspended animation is not cryonics. Cryonics should be discussed [...]

“The crisis of empiricism, expressed in David Hume’s scepticism, was the product of a misinterpretation of knowledge and vanishes for a correct interpretation – such is the outcome of a philosophy grown from the soil of modern science. The rationalist has not only presented the world with a series of untenable systems of speculative philosophy [...]
