UNITY OF LIFE

What is life in general?
Is it functional-based or material-based?
In the west, the religious people may identify life with a strange entity: soul.

TELEOLOGY

Does it make sense to define life with a purpose, end or destiny?
Does science ever talk about purpose?

DIVERSITY OF LIFE

The division between the animate and the inanimate is almost indisputable for people at all ages.
So, within the animate, we have a spectrum of forms, from the virus, plants, cows to humans.
Do they just differ in terms of complexity of organization?

21

PAN-PSYCHISM

There have been influential arguments that everything in the universe is animate to various degrees.
There are also strange arguments to the effect that everything is just the manifestation of one thing.
Need the scientist care about these views?

WATSON AND CRICK

Bio-technology nowadays offers us a lot of possibilities: cloning people and their body parts, altering genes of a living person or a gamete, creating new organisms from scratch. All these are the result of what Watson and Crick had discovered more than half a century ago.
We can now consider how easy in theory we can become what we really want to be.
If we are willing to take the risk of driving a car, what is so immoral and risky about modifying our genes so as to become what we want ourselves to be?
Isn’t it the same as having a tattoo?

CLONING

We have cloned Dolly the sheep.
Some countries might have already cloned a human being.
We can also cloned human organs and parts.
Is the immorality about human cloning, if any, just about the uncertain risk?
What about human dignity?
