Once Ptolemy and Plato, yesterday Newton, today Einstein, and tomorrow new faiths, new beliefs, and new dimensions.

Man has now become an adjunct to perfect and carry forward these conquests.

But, in the name of the experimental method and out of our poor knowledge, are we really entitled to claim that everything happens by chance, to the exclusion of all other possibilities?

Looking back 25 years later, what I may say is that the facts have been far better than the dreams. In the long course of cell life on this earth it remained, for our age for our generation, to receive the full ownership of our inheritance.

As far as I remember, even younger than eight, I have always been guided by reason. Not cold reason, but that which leads to the truth, to the real, and to sane Justice.

The cell, over the billions of years of her life, has covered the earth many times with her substance, found ways to control herself and her environment, and insure her survival.

Man, like other organisms, is so perfectly coordinated that he may easily forget, whether awake or asleep, that he is a colony of cells in action, and that it is the cells which achieve, through him, what he has the illusion of accomplishing himself.

We have entered the cell, the Mansion of our birth, and started the inventory of our acquired wealth.

This attempt to isolate cell constituents might have been a failure if they had been destroyed by the relative brutality of the technique employed. But this did not happen.

For this equilibrium now in sight, let us trust that mankind, as it has occurred in the greatest periods of its past, will find for itself a new code of ethics, common to all, made of tolerance, of courage, and of faith in the Spirit of men.

For over two billion years, through the apparent fancy of her endless differentiations and metamorphosis the Cell, as regards its basic physiological mechanisms, has remained one and the same. It is life itself, and our true and distant ancestor.

Is it absurd to imagine that our social behavior, from amoeba to man, is also planned and dictated, from stored information, by the cells? And that the time has come for men to be entrusted with the task, through heroic efforts, of bringing life to other worlds?

Once Ptolemy and Plato, yesterday Newton, today Einstein, and tomorrow new faiths, new beliefs, and new dimensions.

When I went to the University, the medical school was the only place where one could hope to find the means to study life, its nature, its origins, and its ills.

For the resolving powers of our scientific instruments decide, at a given moment, of the size and the vision of our Universe, and of the image we then make of ourselves.

This familiarity with a respected physician and my appreciation of his work, or the tragedy I experienced with the long, tormented agony and death of my mother might have influenced me in wanting to study medicine. It was not the case.

No doubt, man will continue to weigh and to measure, watch himself grow, and his Universe around him and with him, according to the ever growing powers of his tools.

Small bodies, about half a micron in diameter, and later referred to under the name of 'mitochondria' were detected under the light microscope as early as 1894.

It is the cells which create and maintain in us, during the span of our lives, our will to live and survive, to search and experiment, and to struggle.

Infuse your life with action. Don't wait for it to happen. Make it happen. Make your own future. Make your own hope. Make your own love. And whatever your beliefs, honor your creator, not by passively waiting for grace to come down from upon high, but by doing what you can to make grace happen... yourself, right now, right down here on Earth.

Broad tolerance in the matter of beliefs is necessarily a part of the new ethics.

We're very open and outspoken about our faith and our beliefs. We also talk about our doubts, our moments of insecurities. We talk about it all day, how we're inspired by God. We recognize little miracles every day, and that's how we're raising our daughter.

Customs form us all, our thoughts, our morals, our most fixed beliefs; are consequences of our place of birth.

Quotations are useful in periods of ignorance or obscurantist beliefs.

It remains to consider what attitude thoughtful men and Christian believers should take respecting them, and how they stand related to beliefs of another order.

Don't make the mistake of thinking that you have to agree with people and their beliefs to defend them from injustice.

But there's no reason why we should abdicate our foundational principles because certain groups don't believe in them. You know, no majority should surrender its deeply held beliefs to those who don't believe in anything.

The basic fault lines today are not between people with different beliefs but between people who hold these beliefs with an element of uncertainty and people who hold these beliefs with a pretense of certitude.

It's an indulgence to sit in a room and discuss your beliefs as if they were a juicy piece of gossip.

God help us from those who believe that they are the sole possessors of truth. How we manage at times to agree willingly to become prisoners within our own minds and souls of beliefs and ideas on which we can never be flexible.

What we can or cannot do, what we consider possible or impossible, is rarely a function of our true capability. It is more likely a function of our beliefs about who we are.

In times when religious or political faith or hope predominates, the writer functions totally in unison with society, and expresses society's feelings, beliefs, and hopes in perfect harmony.

Beliefs and values that have held sway for thousands of years will be questioned as never before.

The US constitution's First Amendment rights only cover Americans, but I believe that in a democracy the competition of ideas and free speech should combat beliefs that it does not agree with - more speech and debate, not censorship.
