‘QUO VADIS HUMANITAS?’

We find ourselves in the last decade of this century; no previous century has had such a profound effect on human life. Perhaps no century has produced such a level of apprehension and fear, anchoring them in the consciousness of man. One has become mistrustful. When a discovery becomes known nowadays, the first question is not, ‘Of what use will it be to mankind?’ (as in earlier times) but, ‘What damage will it cause, and how will it diminish our well-being and health?’ Our present state of well-being is bestowed upon us mainly owing to scientific knowledge; this has brought life expectancy up to 75 years, approaching the biologically natural age limit. At the beginning of this century, life expectancy was a mere 50 years and at the beginning of the previous century it was only about 40 years. In developing countries, the curve of life expectancy is also rising, although it lags about 50 years behind ours; meanwhile, our life expectancy is approaching an upper limit. Yet, as never before, we peer apprehensively into the future. This is despite the fact that in the political sector, some of the gravest and most grotesque developments instigated by humanity in this century appear to be in the process of rectification. It is unlikely to be decided in this last decade whether these changes are really for the better.
