MANIPULATION GÉNÉTIQUE D’EMBRYONS HUMAINS

Abstract

Trying to determine if the human embryo is a person, is
one of the questions to which philosophical, bioethical
and biological aspects will come together, the same ones
that necessarily disagree from their particular point
of view. For this reason, a brief review of the various
approaches is carried out applying the principles of philosophical anthropology and metaphysics at all stages of
human life. From these principles it is proposed to build
or build a bioethics that is objective, and that solves the
cases and actions that have to do with human life and its
nature. On this subject there is a first emotional posture
that makes us all be in favor of life and in defense of
embryos, but to build an ethical system we cannot rely
on mere feeling but raise it to the reflexive category and
share the prescription of Diego Gracia, who points out
that the feeling without reflection is blind and that the
reflection without feeling is born dead, so when there are
morals based on a system of strongly emotional values, it
must be subjected to the control of reason, considering
the means and ends. This is what is called the ethics
of responsibility that must prevail at the dawn, of the
solstice and the decline of life. Post-genomic modernity opens the door to wonderful promises about the
real possibility of manipulating in the diagnostic and
even therapeutic perspective the rudimentary «human
being» in the process of formation. From 1953 to today
there have been spectacular scientific and technological
conquests around the structure and function of DNA
(genomic sciences): Non-invasive prenatal screening
(NIPT), CRISPR/Cas9 (Lejeune, 1993)
