Some of the more interesting discussions in the book include: 1. The rising of the carbon dioxide content of the Earth's atmosphere, particularly since the beginning of the industrial revolution, and the need therefore to retain as much as possible the forests on the planet. 2. The 2/5 phyllotaxic leaf arrangement of the tobacco plant, the goal of which is to optimize the amount of light falling on the leaves. The author throughout the book emphasizes the clever evolutionary strategies of plants. 3. The Priestley experiment showing the opposite effects of animals and plants on enclosed atmospheres. 4. The use of electron-spin-resonance spectroscopy to decipher the sequence of events in photosynthesis. 5. The efficiency of photosynthesis in the creation of a molecule of oxygen: eight photons to release one oxygen molecule, a doubling of the number needed from the theoretical value. 6. The ability of chloroplasts to change their orientation to obtain maximum exposure to light. 7. The overwintering strategies of plants. 8. The ability of the cocklebur to flower if the photoperiod is less than 15.5 hours per day, but not if it exceeds that value by more than a few minutes. 9. The absorption spectra of phytochrome. 10. The measurement of the circadian rhythms. 11. The use of transgenic plants to study the control mechanisms of phytochrome. 12. Growth hormones in plants, particularly the discussion of gibberellins. 13. The phototropism of plants. 14. The mechanism by which plants form chemical toxins in response to injury. 15. The production of ethylene after damage to the plant, activating cell division. 16. The reaction of plants to excessive salinity of the soil. This discussion is very important in the context of recent attempts to develop salt-resistant tomatoes. 17. The ability of a single protoplast to produce an entire plant. 18. Recombinant DNA technology and the production of transgenic plants. This discussion is by far the most fascinating in the book. The recent developments in the genetic engineering of plants has to rank as the most interesting in all of scientific endeavor. 19. The ethical considerations involved in modern biotechnology.
In the last sentence of the book the author states that "Plant science has matured, and the age of innocence is over". Indeed his words are a modest reflection of the importance of botany in the world today. Botanists, through the use of genetic engineering, have made incredible discoveries in the last two decades, and will no doubt make many more in years to come, especially in the agricultural sector. But horticulturists, professional and otherwise, also have many things to look forward to in botanical research. As a lover of plants and as an owner of hundreds in my home, I look forward to the new varieties of plants that will be developed in the future using the techniques of genetic engineering.....

In this book, Dyck, a Population Ethics professor at Harvard university, examines the various legal and philosophical arguments thrown up in favor of physician-assisted suicide (PAS), assesses different types of treatment available for the suffering and terminally ill, establishes the religious and moral framework which upholds the sanctity of life, and concludes with a look at Christian concerns over sickness and dying.
On the philosophical front, Dyck details recent defenses of PAC, and shows how major moral and philosophical shifts have taken place to allow such defenses to take root and flourish. A major shift in how we view human nature undergirds much of the euthanasia debate today. That is, we have shifted from an emphasis on the sacredness of human life to autonomy as the highest good.
For example, thinkers such as Hobbes, Locke and Kant understood human nature as including a strong sense of self-preservation, not just of the species, but of one's self. Mill, on the other hand, adopted an autonomous hedonism: self-happiness is the goal, regardless of how that is played out. Unfortunately, the thinking of Mill and others has tended to win out over the traditional view.
That, coupled with the rise of secularism and the collapse of religion, has led to a quality of life ethic replacing the sanctity of life ethic. These differing views of human nature and the social good underlie the differences found in the euthanasia debate today.
These differences take practical expression when we decide whether to utilise palliative care or simply administer a lethal injection. The two different actions reflect two different views of humanity. Dyck's second chapter examines the moral differences between comfort-only care and PAS. While there may be some overlap (pain relief can hasten death), the two are quite different in moral terms.
A major difference has to do with intent. What is the primary goal: to preserve life, or to end it? A lethal agent is introduced into the latter, making it ethically very different indeed.
Chapter three deals with moral rights and human right in the PAS debate. Traditionally it was held that we all have a moral responsibility to preserve life - others and our own. Suicide (and PAS) thus was seen as an abrogation of that central moral responsibility. Counter-arguments about autonomy and freedom of choice do not however curtail that responsibility, argues Dyck. The over-emphasis on choice and freedom may sound good, but it often leads to disastrous outcomes.
That is, what a society allows intellectually, and more importantly, legally, will impact on how individuals respond to those conditions. One study found, for example, that not one AIDS patients in England who wanted to end their life did so, while 30 % did in the Netherlands. The reason? PAS is illegal in England and hospice care widely available, while the exact reverse is true in Holland. So those who wish to legalise PAS will inevitably see a rise is such cases. Bad thinking leads to bad laws which leads to bad outcomes.
The better way is to show real compassion to the sick and dying, instead of wishing them a speedy exit. Dyke concludes this volume with a look at how Christian beliefs and practices are the best response to suffering and death.
The Christian world view has always had a high view of human life and its inherent dignity. This shows through in many ways, from missions of mercy to the establishment of hospice care. Indeed, both hospitals and palliative care largely spring from Christian roots.
Genuine compassion treats all life with respect and dignity, and does not judge life on the basis of functionality or usefulness. It is the harder, more difficult path to follow, but is the more loving and just path.
The transformation of our thinking on human worth is accelerating apace. So too are the corresponding calls for PAS and a host of other anti-life initiatives. Calls to legalise euthanasia will only become louder and more frequent. Those who seek to uphold the sanctity of life need to be ready for these challenges. Becoming informed about the euthanasia debate is part of the preparation. This important volume will help greatly in that task.

This can be a difficult read, as you would expect. Some of the legal and real estate squabbles are obscure. On the other hand they involve people like John Dudley, father of Robin, who also turns out to be Plantagenet-Lisle's stepson, and Edward Seymour, brother of Queen Jane. (Both these men, incidentally, become Lord Protector during Edward VI's reign.) And it's fascinating to read genuine letters written by the administrative power, Thomas Cromwell, who is probably the best writer of the lot, though clearly very calculating and political. We also watch as two of Arthur's stepdaughters, through his second marriage to Honor Basset, are forced to vie for positions as ladies-in-waiting to Queen Anne Boleyn, his stepson James Bassett vies to get into the college of Navarre so that he'll be hobnobbing with Princes, future Kings and Cardinals, and a perfectly ordinary courtship between his sister Mary and the son of a French business partner goes sour because of the Reformation. Meanwhile the daily routine of ordinary life shows through with everyone throwing gloves and lace and coats and animals, some as pets, some to eat, at each other, and describing the various states of lands--that they're fighting over, live on, or are absent from. Different readers will get different things out of the wealth of material here. Though everyone will learn a little bit more about why Cardinal Reginald Pole was so important to the machinations of Tudor times. There's even a nice picture of him.
