Dear Friends,
This Sunday we are discussing: Do we inherit experiences from our ancestors?
At face value this question falls within the province of science 
especially biology moving on to psychology, neurology and genetics. So 
what is the philosophy of this question?
As a topic this is quite an interesting one and even popular; indeed a 
quick search on the internet will list quite a few articles including 
popular style article. One reason, maybe, why this subject should be 
interesting is that the more we move into large cities the more we 
become anonymous individuals. But our past is something very much our 
own and very much a fact of life and reality. Our past is ours and we 
are not that anonymous in the past. The question whose life is a fact 
and whose reality are we talking about?
Of course, by experience we cannot mean the actual sense perception when 
a causal chain of events are happening in real time that later we can 
call experience. By inherited experiences we can mean memories of the 
experience, effects of the experience, and of course biological changes 
to our body as a consequence of the experience which are then passed on.
Regarding the nature nurture debate, our parents, or even ancestors, can 
only pass genes that are present in them at the time of conception. 
Later gene changes can probably only be passed by complex circumstantial 
events. Maybe say (and I am speculating here) a virus that affects one 
of our parents, say by changing a gene, will also affect us by virtue 
that we have inherited 50% of the genes of our parent.
However, what we know for sure is that a foetus can affect and maybe 
change genes of the mother; after all a foetus is a foreign biological 
body in the womb and hence in principle can affect adversely the mother. 
This might for example happen when the foetus inherits a gene from the 
father that causes a change in a particular gene (eg a blood/bone marrow 
genes) via the foetus the gene is passed on to the mother. This chain of 
causal events in well documented in the medical literature.
But there is also another route where an experience is passed on to 
future generations. Family behaviours, maybe, such as rituals or as 
memes can and do affect future generations. For example, cooking 
traditions is a good case in point. When a member of a family has high 
blood pressure it is very common for the family not to use salt in the 
food. Of course, some members of the family might inherit high blood 
pressure, but not necessarily all children of the parents will inherit 
this disease. However, those with normal blood pressure might get used 
to food without salt and this way of cooking will be passed on by this 
particular person. Indeed it might be argued that this family do in fact 
experience the perception of their ancestors; eating unsalted food is a 
unique experience.
Returning to the theme of experience we might be forgiven in thinking 
that by experience these have to be some sort of action packed events. 
But not necessarily, since our mental events (thinking) are also 
experiences and physical experiences. Of course, not all cases of 
intelligent parents manifest themselves in intelligent children, or even 
more intelligent children. There are more factors that shape 
intelligence besides genes; our environment and circumstances play a 
huge role.
There are many ways that our ancestors affect us and our behaviour 
today. Of course, those who have children today will be affecting future 
generations. But this does not mean that we are determined or wholly 
determined by past generations. It only means that some traits, due to 
experiences of our ancestors, might affect us. But we are as likely to 
be affected by the experience of our ancestors as much as our new 
experiences, including experiences of our partners.
But even then some experiences might be unique and therefore very hard 
to repeat them or to be repeated. Not many people can claim to have 
inherited experiences from one of their ancestors who had visited the 
moon. But many experiences are practically the same: I have already 
mentioned food without salt.  Another experience is living in hot or 
cold climates: the temperature is the same, how we cope with it is the 
private experience.
Indeed, the domain of our topic is biology and related sciences, but 
language is the domain of philosophy. Clarifying what we mean by such 
interesting questions as our topic is the scope of philosophy. If the 
devil is in the detail, philosophy must surely be the devil; maybe?
(note there are many more articles on the subject)
