I.m.o. nobody really wants to feel depressed...to the point of taking his/her own life. I am sure that affected people actually want to feel better about themselves and their lives. Seeing that it is something that can be managed by means of treatment, should that not be the starting point..? Future generations will probably have the luxury of undergoing genetic screening tests at an early age that will allow high-risk individuals (depressed/anxious, psychopathic, Alzheimer, etc.) to be treated in time.

Just getting back to posts #3 & #9. It appears that they may in fact be addressing each other to some extent..? Suicide is being frowned upon because of cultural (incl. religious) norms and because unaffected humans find it extremely difficult to understand how any person can take his/her own life. The OP seems to want to delve into the question as to whether it should be seen as "abnormal" behavior and whether affected people should get treated in order to prevent suicide (severe depression is treatable and will become even more treatable in the future)?

@ Phi for All & Delta1212: Seeing that you were/are dealing with the issue of moderate Democrats/Republicans, I have been struggling to understand the growing emergence of right wing extremists. I am not a USA citizen, so not entirely informed, but it seems to have started after Obama was first elected. At this point it appears that the majority of Republicans have moved away from the moderate middle ground to the right though, which would explain how the likes of a Trump end up being the Republican candidate. But how has this happened and more importantly, what are the prognosis i.t.o. balancing out these extreme sentiments? I know the American demographics have been changing quite quickly. Has this something to do with a right wing resurgence...and will it subsequently lead to a balancing act of some sorts? There seems to be a polarizing effect going on and the growing racism and bigotry appear to be symptoms thereof..? That being said, the same kind of thing is happening in European countries. Recent elections in Austria as well as the Brexit vote, among others, seem to indicate a similar move towards the right. In the case of Europe it has a lot to do with the massive inflow of Middle Eastern and North African nationals though.

@ nimae: That is your opinion, correct, and not based on facts per se..? @ johnmusic: "Stardust with opinions"...lol, I like it.

As far as I know it is a genetic predisposition; pretty much the same predisposition that yields depression. If you are born with it, you will be vulnerable. Environmental factors (i.e. when things do not go according to plan) trigger it. The same goes for alcoholism and a range of so-called "personality disorders", even homosexuality

Yeah, I watched it too. Looking at it as an outsider, I am astounded every time I have to watch- or listen to Trump. I just can't believe that there are actually people who will vote for him to become the president of the USA. Not that he stands much of a chance by all indications, but still... Sorry for repeating myself but he is just such an inferior specimen compared to Hillary Clinton and that, in a sense, is pretty ironic if not downright sad...a male chauvinist parading his ignorance, narcissism and bigotry in front of the whole world while being outclassed and outwitted by his female opponent...without him even noticing it. She did a fantastic job in showing grit, determination and above all, being able to convey a great deal of sense in a well articulated manner in the short time allocated to her. Just consider the two closing arguments as an example. She also made very good use of opportunities to compare their respective track records (and those should be telling). He, on the other hand, was not saying much new. The same old rhetoric, the same old (unsubstantiated) blame game against Clinton, Clinton & Obama. He has no clear vision, just empty promises and dreams of some sort of American grandeur that gonna happen because he thinks it will..? And the audacity to acknowledge: That, considering his stance against outsourcing or importing cheap labour/material, he did it himself...Why? Because the Clintons and Obama allowed him to; That he used loopholes to avoid paying taxes. Why? Because the Clintons and Obama should have prevented said loopholes; And last, but definitely not least, hinting towards possibly not accepting the outcome of the elections...like in next time on the Trump presidential reality show, watch this space folks... Gosh, this coming from a presidential candidate..? Seriously!

I will go through that thread again, but I followed it before and contributed to it (on page 3, for example). Both ajb (in the opening 4 pages, especially on page 4) and later VandD (on page 7), among others, raised some pertinent points w.r.t. block universe model(s). In the mean time, talking about practical features of the block universe and its implied non-compliance (for lack of a better word) with quantum behaviour, see this post.

I agree with imatfaal. Some of the discussions (e.g. free will, determinism, religion and similar topics) could potentially unsettle the mind's comfort zone, so to say, and may change (for better or worse) the way one perceives the world around you. One may just find yourself on a slippery slope before you realise it. Sometimes it is better to distance yourself (emotionally, psychologically) from some of the unnerving ideas that are being thrown around in some of the threads.

As somebody previously suggested, you really do need professional help. From what I can gather you have a range of classical personality/psychological disorder symptoms...these are treatable...and more importantly, you are not to be blamed...especially not by yourself (remember that gene/environment interaction..?).

Let me just clarify what I meant by this - the pen is a "stationary prop" in its spatial environment, i.e. it does not move in relation to its surroundings. It is merely being "copied" (I should be careful with using too many analogies here) from one event to the next, but as I explained there may be other factors of said event (or "image"), for example the ambience, that might have changed (who knows, perhaps a bird started chirping outside in the next observation of "stationary" pen). It is on this point that we keep on missing each other. The way our brains interpret reality is indeed akin to presentism (as you explained before and again above), but the actual reality may be different to the way our brains interpret it. Actual reality according to eternalism/determinism in a 4D block universe implies that all events are pre-existing and laid out at different coordinates of spacetime. They are all equally real, carved in stone, frozen. etc. We are merely experiencing/observing said "sequence"; hence my use of the way our brains perceive an animation...which it interprets as an ongoing event (a moving now) opposed to different events (many nows) being experienced/observed. A natural living and evolving environment should not deter us from the possibility of a many-now reality. Perceived causality, randomness, changes, us being reliant on oxygen could all be an entirely natural (but deterministic) sequence within symbiotic eco systems in said reality. (You may want to think of living and breathing actors playing their parts in the movie..?). Tim, there have been many instances where the block universe came up for discussion in a number of threads in this same General Philosophy category. As far as I have seen they all dealt with certain aspects thereof. I don't know if you want to start a new thread and merge all the relevant posts into it as this current discussion may indeed be moving a bit off topic..? Said thread should attempt to differentiate between the various models (presentism, eternalism, growing and evolving).

With your math skills you will "intuitively" end up ticking the right block. The "now" is made up of an observation/experience of an event at a specific coordinate (a slide in the animation example). The "now" should not move as presentism suggests (IOW that way of thinking might indeed be wrong), rather it is the continuous observation of many "nows" that give the impression of movement (animation)...as per eternalism. PS. Michel, just note that I previously mixed up Tim's example of the pen with your glass of water (as I mentioned in my previous PS note). The pen was indeed stationary (sic), but a separate observation thereof would reveal a slightly different looking pen (different light on it, or slightly different angle, or something like that).

Lol...I enjoyed this ^ An observation of what is seemingly a 3-D object captured/embedded in a slice of spacetime at a specific coordinate. One coordinate "back" will give you the same pen at a slightly different distance (as per your original illustration) and thus per implication at a different (space)time. One coordinate "forward" implies that the same pen will be observed at a ever so slightly closer distance (at a different coordinate of spacetime). Think about an analogy, for example a set of animation flip cards...on each card (coordinate) a different image (event) already exists. We are observing our lifeline as an illusion of the fast moving set of animation cards. (I used the same analogy in the other thread referred to earlier where I discussed it with Strange). I.t.o. eternalism all these events are equally real...time is laid out, or there are many "nows"...even though we are unable to rewind or fast forward. I.t.o. presentism there is a distinction between an event in the past, present, and future (an event in the past was real, an event in the present is real, and an event in the future will become real). Notice that the “now” moves. This is where I want to insert this quote that describes it quite well: ...it raises the question which has puzzled philosophers: “How fast does time flow?”. If the “now” moves then it must move with respect to some time reference. So is it moving with respect to itself? Surely not. To say “Time moves at the rate of one second per second” is meaningless. Rather, the rate of time flow would have to be measured with respect to some secondary, external time reference. However, in our earlier discussion on this page it was stressed that there was no clock outside the universe, so there could not be any such external time reference. It is simply logically impossible for there to be a moving “now”. Time does not “flow”! (Time, Free Will and the Block Universe) PS. I might have confused Tim's pen with Michel's glass of water...but it is all the same.

There are indeed a number of variations of the block universe model, presentism, eternalism, growing (which is not the same as eternalism) and evolving (I must admit that I am not too familiar with the last-mentioned and how it differs from growing). So perhaps we should all (including myself) be a bit more mindful of how we interpret these models. That being said, it first appeared to me like Tim has pinpointed how our brains adapt in order to make sense of reality, including the (illusionary) flow of time. It also seemed to me as if he concluded that presentism best explains our (intuitive?) interpretation of reality (which is understandable), even though it may in fact be an illusion of sorts, but at the same time he then stated that eternalism is "stemming from a natural confusion in our minds". It sounds somewhat like a contradiction, but maybe I am just not following the logic behind his explanation (Tim, don't bother to explain it again...I will go through it step-by-step). Einstein, who of course knew a thing or two about GR & SR, seemed to have been pro-eternalism and pro-determinism. Strange and myself have recently discussed the ins and outs of said model in the thread "How to convince somebody they don't have free will?" in this same General Philosophy category...from post #22 on page 2 of that thread inbetween other posts related more to the OP. (I am sorry that I cannot insert links, but I am currently working on a laptop with an old browser that would not allow me to copy and paste anything, or to insert quotes). Anyone who is keen to better understand the implications thereof is welcome to read that, or at least the short article (Time, Free Will and the Block Universe) that I linked in that post #22.

Perhaps illusion and confusion are in the eye and mind of the beholder, no..? I do. Moving like in us moving along was a figure of speech. It is more like us observing (or "moving our observation") of different static events embedded at different coordinates. In said (4D block universe) model time and space are laid out, we are just observing/experiencing it slice by slice.

I tried to follow your logic up to this point (and reserve my opinion)...but I need to ask if you meant that eternalist philosophy stems from a natural confusion in our mind, or whether eternalist philosophy creates a natural confusion in our minds? Possibly because there is no flow of time and our perception of moving-, or flowing time is us moving through "static" (space)time.

This snippet that I already quoted elsewhere may be relevant here too:

Tim, it seems as if you have made some great progress as articulated in your most recent posts. So are you starting to realise why our brains intuitively struggle to understand the possibility of a 4D block universe, but that we should never allow our perception of reality to obscure reality itself?

Maybe start here...where did the energy come from for this universe..?

@ lyudmilascience, I hear where you are going with this but could it not potentially be more problematic to want to distance ourselves from animals...as if we have some higher purpose..?

Yes, indeed! As for our lifeline(s), I see it as similar to one of those animation flip cards that one flips through, page for page (event after event), an embedded development (like a moving picture) within the bigger universal 4D spacetime "hologram"...it becomes almost like a cross section across various coordinates/locations on said "hologram" (not virtual per se).

Personally I prefer to think of it as a block hologram of something akin to a massive map with (spacetime) coordinates placed in a dark environment...as you point a flashlight to it, it illuminates a specific location...an observation of a pre-existing place (an event) at/on a specific coordinate. To say the embedded "information" (all events) on said hologram map has an actual beginning or end, past or future, does not make sense. Thank you, iNow.

As Jerry Coyne stated in the article that I referenced on page 1 of this thread, we are marionettes dancing to the strings of our genes and our environments.

Darn...it happened again...I intended to press quote below your post and I got the down vote instead. SORRY - it was not my intention. Referring to the above - no, definitely no meta-time. I think we may be misunderstanding each other somewhere along the line..?

Lol, I recently tried to explain this to my kids (who are in primary school) using the analogy of a firm trampoline with different sized/weight balls being placed on it...

I agree with you (and stated as such) that the evidence continues to mount. But the following is an excerpt taken from the above article: "The field remains highly controversial. There is no consensus among researchers about the significance of findings, their meaning, or what conclusions may be drawn. The precise role of consciousness in decision making therefore remains unclear."
