If a single cell, under appropriate conditions, becomes a man in the space of a few years, there can surely be no difficulty in understanding how, under appropriate conditions, a cell may, in the course of untold millions of years, give origin to the human race.

Surely if a single cell may, when subjected to certain influences, become a man in the space of twenty years; there is nothing absurd in the hypothesis that under certain other influences, a cell may, in the course of millions of years, give origin to the human race.
Herbert Spencer
What I write is full of infirmities. I have been in solitary confinement for twelve months and in a death cell for three months, deprived of all facilities. I have written much of this by resting the paper on my thigh in unbearable heat. I have no reference material or library, I have rarely seen the blue sky. The quotations are from the few books I was permitted to read and from the journals and newspapers you and your mother bring once a week during your visits to my suffocating cell. I am not making excuses for my deficiencies but it is very difficult to rely on a fading memory in such physical and mental conditions.
I am fifty years old and you are exactly half my age. By the time you reach my age, you must accomplish twice as much as I have achieved for the people.Zulfikar Ali Bhutto
In biology the Cartesian view of living organisms as machines, constructed from separate parts, still provides the dominant conceptual framework. Although Descartes' simple mechanistic biology could not be carried very far and had to be modified considerably during the subsequent three hundred years, the belief that all aspects of living organisms can be understood by reducing them to their smallest constituents, and by studying the mechanisms through which these interact, lies at the very basis of most contemporary biological thinking. This passage from a current textbook on modern biology is a clear expression of the reductionist credo: 'One of the acid tests of understanding an object is the ability to put it together from its component parts. Ultimately, molecular biologists will attempt to subject their understanding of cell structure and function to this sort of test by trying to synthesize a cell

I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars.
