Justice Cruz, Manolo Quezon and “A Natural History of Sex”

I have belatedly followed the brouhaha between Justice Isagani Cruz and what he believes are gays’ role in society and the response of some of his critics such as, “The Explainer” Manolo Quezon.

In a democracy, ideas are open for debate and I know that a respected jurist like Mr Justice Cruz knows what the limits of freedom of expression are. But while Justice Cruz and Mr Quezon have a right to their opinions, I’ll dish out some of my own.

Natural scientists and social scientists will have to really define what being gay is. Under the cold logic of Darwinian sexual selection, is gayness functional? What does “functional” mean? Now before I inflame some people, it would be best for them to read Darwin’s “Descent of Man”.

But reading Adrian Forsyth’s “A Natural History of Sex” may be a good starter. I found this book in the really, really bargains pile at the recently concluded Philippine Bookfair in Manila. Forsyth is a leading biodiversity scientist based at the Smithsonian.

Now the whole idea of sex in the animal, plant and bacterial kingdoms have been always controversial since we tend to relate how they do it with how we do it. Fortunately or unfortunately there is diversity in sex and how to do sex. This is probably Nature’s joke on our preconceptions. And Nature’s joke is the stuff that makes cocktail parties bearable and fun.

Neo- Darwinian sexual selection while intuitive rests on the idea that we should be able to pass on our genes at all costs. All our evolutionary advantages are geared towards maximizing reproductive success, thereby and consequently maximizing reproductive fitness. This is where the question of being Gay really lies. For under classical Sexual Selection, gayness makes no sense.

Homosexuality in the animal kingdom is the subject of much research. Much of the research has become ideologically coloured. For the natural scientist, is gayness biological? And if it is biological, what fitness does it confer? In science, we practice our profession under a current paradigm. And in this stage of scientific history, Darwinian sexual selection is the paradigm. The job of scientists is to document instances that are exceptions to the paradigm. And this is where some of the gayness research has focused on lately.

Of course, there are documented examples of homosexual behaviour in animals. The question is whether this leads to a more successful heterosexual strategy or something else.

Many scientists believe while there are observed homosexual behaviour these tend to prepare the animal for eventual heterosexual behaviours. Most of these “gays” are adolescents who are yet to compete on the sexual selection arena. This is the “gay developmental” hypothesis. The adolescents lose their gayness once they are mature and able to compete for sex.

The reason why this gay research needs to be addressed is that homosexuality in animals may have evolutionary continuity for humans. This is a central tenet of Darwinian Evolution. However, the subject has become politically sensitive for obvious reasons.

But then along, the whole concept of “gay” is something human. I don’t think a parrot who mounts a same-sex parrot would think he is gay. Thus the idea of using this animal gay research to defend the thesis that gayness is normal is wrong. Under the cold logic of Darwinian evolution, there is no such thing as “normal”. Without teleology; evolution cannot be limited by moral or ethical bounds. The only “end” of evolution is itself. Animals may practice infanticide and even terminate pregnancies. This is to maximize reproductive fitness. Most humans gay and non-gay would abhor these as abnormal. Devout believers of religion may be aghast to learn this. But it happens in nature and there is no moral colour to it.

I do appreciate the opinions of Justice Cruz, although I disagree that in his latest response to his critics, he labeled “gays” as feline. I think this is a disservice to cats. And for Manolo Quezon and other likeminded critics, name calling and taking logical flipflops do no good for the honest discussion of homosexuality.

President Manuel Luis Quezon's Code of Ethics

Being a denizen of Kyusi, in honour of the man who gave my city its name and for being the most colourful prez the Philippines ever had, I have the pleasure to post Manuel L Quezon's Code of Ethics on his birthday. Let us profit from the wisdom of the Kastila.

1. Have Faith in the Divine Providence that guides the destinies of men and nations.

2. Love your country for it is the home of your people, the seat of your affection and the source of your happiness and well-being. It's defense is your primary duty. Be ready to sacrifice and die for it if necessary.

3. Respect the Constitution which is the expression of your sovereign will. The government is your government. It has been established for your safety and welfare. Obey the laws and see that they are observed by all and that public officials comply with their duties.

4. Pay your taxes willingly and promptly. Citizenship implies not only rights but obligations.

5. Safeguard the purity of suffrage and abide by the decisions of the…

Simoun's lamp has been lit, finally.. not by one but by the many!

"So often have we been haunted by the spectre of subversion which, with some fostering, has come to be a positive and real being, whose very name steals our serenity and makes us commit the greatest blunders... If before the reality, instead of changing the fear of one is increased, and the confusion of the other is exacerbated, then they must be left in the hands of time..."
Dr Jose Rizal "To the Filipino People and their Government"
Jose Rizal dominates the Luneta, which is sacred to the Philippine nation as a place of martyrdom. And many perhaps all of those executed in the Luneta, with the exception of the three Filipino secular priests martyred in 1872, have read Rizal's El Filibusterismo. Dr Rizal's second novel is a darker and more sinister one that its prequel but has much significance across the century and more after it was published for it preaches the need for revolution with caveats,  which are when the time is right and who will instigate it.

Flame trees in bloom

The hottest summer courtesy of El Nino in at least 10 years gave runners and walkers in the University of the Philippines Diliman campus a visual treat. This year the flame trees Delonix regia are in full bloom!
In past summers it wasn't as hot and dry so the trees did not shed their leaves and few blooms were produced.
It is the tropical version of the Japanese Hanami or the Cherry blossom viewing season. While Hanami tells us the fragile impermanence of beauty, the flame tree hanami tells us that summer burns but soon it will all be over.
