I recently had to explain on another forum why the hell I said that plants are "things" and therefore cannot be "respected". I hope this can help here.
-Hey people,
I was the “Cartesian guy” who referred to plants as “things”, also saying that we cannot “respect” them for the same reason we cannot “respect” a car, a chair or a spermatozoid.
English is not my first language, and I still have many flaws with it. Why am I saying this? Because I remember reading somewhere, about the “living things” that inhabit this planet. So I assumed that, in English, you make a difference between “living things” and “living beings” (if this is misguided please correct me.) This made sense to me, since I never felt comfortable calling a tumor a living “being”. Yep, they´re very much alive, but I think they are living “things”.
Why do I think this? Because I believe that it is an absolute necessity to be sentient and self-aware, to be a “being”, a “somebody”. Sentience comes from the capability to feel pain and pleasure. To be aware of these unique “experiences”, to have unique “interests” –the concept of “consciousness”- form a part of every sentient life. An “individual” is, therefore, born.
As far as human knowledge goes, there are many characteristics that are essential to be a sentient being (nervous system –be it central, peripheral or gangliar-, benzodiazepine receptors, endorphins, etc.)
That´s why we say, that plants are not sentient. If there is no sentience, there are no “experiences”. If there are no “experiences” there cannot be “interests”. If there are no “interests” there cannot be a “somebody”. If you are not a “somebody” you´re a “something”. That´s why I said that I believe plants to be “things”. I didn´t mean that they are the same as a TV or a table. They are alive, of course. But that doesn´t mean they are “somebody”.
For example, I am a sentient individual. I´m made of billions and billions of living things. Nevertheless, all of those billions and billions of living things make just ONE living “being” –ME-.
My blood cells are alive, but they are not sentient, they have no “conscience”, they have no interests of their own. My spermatozoids are alive, but they are not sentient, they have no “conscience”, they have no interests of their own. I do depend, more or less, on them but they are still living “things”. They are a part of ONE living “being”.
I think it might be important to say that “sentience” is not equal to “sensitiveness”. EVERY living form is “sensitive”. They are sensitive to external conditions, and they respond to them. This is how they stay alive, how they reproduce, etc. But, as I wrote before, “sentience” is a whole different concept. To acknowledge that plants are “sentient” we would have to change the very definition of “sentience”.
And we cannot forget that “sentience” works as a defense system. This allows a sentient being to run away or fight back to whatever might be harming her/him. It is also associated with memory, so the sentient being can avoid the same harmful situations. The notion that “sentience” would serve no purpose to plants, logically follows.
Furthermore, there are some animals that have been proved not-to-be sentient (like sponges for instance). There are many other animals that we do not know for sure if they are sentient or not, like some insects.
We can also see this clearer from other human beings. For example, someone who has lost mobility (sentience) below her hips can tell you, right away, that she doesn´t feel pain if you do a little cut on her legs. Nevertheless, her body will have a reaction (cause of its sensitiveness) and will probably heal that cut. But that person didn´t feel pain at all.
She is, indeed, a sentient being. Her legs are still a part of her body. But the connections that make “sentience” below her hips possible are not longer there, so she cannot feel pain.
This is why, I believe you cannot “hurt” a plant – or a blood cell, a tumor, a spermatozoid, a brain-dead human, a chair, or a car-. Some of them are alive, the others are not. But all of them share at least one characteristic. They are not sentient. For the same reason, I believe that since you cannot “hurt” or “please” them, you cannot “respect” them.
This doesn´t mean that I will go out and kill every plant I see, or cut the legs of a human who lost mobility below her hips or destroy all of my blood cells. Of course not.
I do not believe that “sentience” is some kind of “justification” to destroy what is non-sentient. Not at all. As i´ve said earlier, I understand that everything in this world (and even on this universe) is connected, that everything depends on everything and so on. It would be absolutely foolish to think otherwise (yet, this foolishness has taken over the majority of the human population.)
Maybe my notion of who or what you can “respect” or not it´s too intricate, pseudo-philosophical and/or pseudo-intellectual. To be honest, I do talk about “respect” towards plants or even “nature” from time to time, when speaking to others about the absolute necessity of living in harmony with everything in this world. I talk about “respecting” plants by not killing them or destroying them without a true necessity. I think it is a better way to communicate it to others, for the sake of the arguments –otherwise I would have to say all the garbage I´ve written here already!-
If you believe there is something deeper, that somehow represents some kind of "consciousness" or "sentience" on plants on another level (maybe spiritual), I can`t really argue. I do not know anything about it (sadly, I`m too mundane for that.) But, if that is what you believe, the words you`re using ("consciousness" and "sentience") are not being used properly.-
