"since life is considered to be a gift. "

Quick, someone call the cliche patrol.

----------------------------------------------------------------
The philosophical implications of suicide, in my opinion the universe or "universal laws" or rules by which are inherently "right" would say that it is not good to take ones own life, since life is considered to be a gift.
----------------------------------------------------------------

Taking a purely non-religious view on this (as I am prone to do) I, personally, would hesitate to say that life is a gift by univeral law. On the contrary, I would say that life is more a
matter of fact. Every atom can be said to be alive, if life is defined by the ability to act on one's one. Although an atom "acts" due to simple magnetism (positively charged particles interacting with negatively charged particles) that basic unit makes up all matter itself. Since the universe that we can percieve is comprised entirely of matter (stars, planets, land, water, etc) by this definition everything is alive.

This being said, life itself ceases to be a "miracle" and merely "mundane."

Also by this definition, the taking of life has little meaning since even killing someone or yourself does not stop an atom from "acting." True, the body takes on different forms such as decay, however that is merely the transferring of one state to another, since it is a universal law that all things in the universe are comprised of energy and the amount of energy in the universe is constant.

Thus suicide itself has no meaning unless a moral context is placed upon it.

That being said, as Candace pointed out, different cultures of different belief systems view suicide differently (man, that's a loaded sentence ;) For instance, in feudal Japan, suicide was considered an honorable act of a samurai who failed to protect his master, whereas those who chose the opposite were called Ronin (although my feadal Japanese history is rusty, I believe the name meant literally either masterless warrior, or something similar to lost soul, although I could very well be wrong about this.)

In my personal opinion, which is pretty much psychological, premeditated suicide (as opposed to the "crying for help" form, which I will discuss in a moment) is the result of severe emotional distress, in which the survival instinct is either consciously or subconsciously "turned off." It is like a fatal run-time bug in a computer system.

Suicide defined as a "cry for help" is another psychological matter entirely. In this case, the intent, be it conscious or subconscious is not to die, but to make others see that one needs help, for whatever the reason, with helping themselves. The survival instinct is still "turned on" in this case, as in most of these suicides death tends to be slow enough for the person to be able to found before it is too late, whether their finding happens or not is beyond the scope of my argument. This form is much more common and pretty much accepted as THE reason for suicide.

To say that any discussion consists of, or lack of, excitement seems, to me, a poor reason for or against the discussion. Interests regarding concrete topics can be just as intellectually rewarding as abstract topics. It all depends on one's tastes.

This being said, the capacity of conception is an interesting topic none-the-less. The ability to imagine something and create it physically from the thought, is a limitless trait.
