• A first cause is logically necessary
    When something is a first cause, it is an uncaused thing which then enters into causality. There is no limitation as to what a first cause could be, as it has no prior explanation for its being. It is unlinked from determinism as to why it exists. However, once it exists, its interactions with other existences then involve causality, or determinismPhilosophim

    I've always required examples to flesh out philosophical or mathematical ideas, so I will return to the causal chain which is defined in a region of the complex plane. My colleague at Trondheim proved the theorem I have mentioned, but later I proved a much simpler version,changing the hypotheses slightly.

    Think of a large disc in the plane, full of points,z, and each individual function in the chain taking any such point and producing another point in that disc. Assume that each of these functions draw any two points in the disc slightly closer to one another. Then, when you start the chain you can use any point in the disc as a "first cause". The chain will converge to a single value of z within the disc, but the degree of accuracy of that limit will vary depending upon original choice. That is to say some values of z as first cause will take longer to get close to the ultimate limit. Bigger values of n.

    (In fact, in a paper of mine in the Proceedings of the AMS many years ago I showed that if the individual functions approach a specific function, f(z), one may be able to choose a "first cause" that will get the ultimate result the fastest.)

    Another recommendation: Take up Zen under the tutelage of a Master. This would give your life a rigid focus, enforced by the physicality it employs. You will change if you take the practice seriously. I've seen it happen.

    Why is it always better to cease to exist.

    Keep thinking "It is better to exist" You have to corral your thoughts and Zen will do the job if you persevere.

    The steps in a dynamical system or causation chain occur at time intervals. Are there chains that display instant movement, like instant velocity? This involves smaller and smaller times between steps. Here

    So in a way of speaking, the images emerge form some, but not all, of the equations?Banno

    There is always an image arising in the manner I have described. Even an empty frame. I never know what will materialize from a mathematical procedure ( I don't do fractals or other well-known imagery). The math procedure I use is not one others use to the best of my knowledge. Mine is intimately connected to cause and effect chains. Not simple iteration of a complex function.

    And since all change requires timeMetaphysician Undercover

    This depends on the meaning of the word "change". Most usages do require time to complete, but if one thinks of "to change" is "to differ", then time need not be a factor.

    dy/dx = 10 vs. dy/dt =0 if x is not a function of time.

    So which is it: is the butterfly reducible to the equations, or does it emerge from them...?

    Isn't emergence no more than Emperor Reduction in his new clothes?

    (@jgill, any thoughts?)
    Banno

    Not a lot. I can only refer to my own "creations", that are observable in the complex plane. By the way, I program from scratch in BASIC, being old with little time to waste on a plethora of languages, several of which (Fortran, Pascal, . . .) I have used in the distant past.

    There first is a defining mathematical procedure giving a point in the complex plane for each point in play. The procedure can be very simple or very complex. In both cases one paints pixels in the plane corresponding to some aspect of the resulting point, like size of its modulus. Point by point the process paints a picture.

    Philosophically, one can rather easily go from the procedure to the picture, obtaining a visual account of the feature you are describing, like size. But, it is virtually impossible to start with the big picture and deduce the mathematical procedure. Viz. the image above. So the imagery emerges from the mathematics.

    Sometimes the math leads to chaos upon iteration. Other times interesting patterns emerge. So, images emerge from math, but not the other way around (usually). I don't see reductionism in play here.

    The Lorenz attractor is a case where patterns are affected by attracting fixed points or sets of such points. In much of the math I have done infinite compositions - infinite causal chains if you wish - take points toward attracting fixed points. There are also repelling fixed points where you can guess what happens by the title of the point. And of more complexity there are indifferent fixed points that both repel and attract.

  • Spontaneous Creation Problems
    An assignment of causation does not exclude the possibility of other things having the same effect. So in the example above, saying that heat causes water to boil does not exclude the possibility that something else as well, such as a drop in pressure, could also cause water to boil. That A is judged to cause B does not exclude the possibility that something else might also cause B as well.Metaphysician Undercover

    :up:

    Now, I ask you to use logic, and see with your mind, logically, that it is possible for there to be time passing without change occurringMetaphysician Undercover

    This reflects what Minkowski spacetime infers. This is referred to as being at rest in a particular frame of reference.

    However, time passing, itself, is not observed.Metaphysician Undercover

    Yes.

    I love causality. Most of the math exploration I do these days is mathematical analogues of causality chains in the complex plane. So, is philosophy very much invested in physics? Should it be? Is philosophy equipped, in general, to circumvent details and pull quantum tricks out of its big hat?

  • Spontaneous Creation Problems
    Virtual particles are not, currently, "directly observable." They have effects that can be observed, which is why the idea has gained currencyCount Timothy von Icarus

    In the one-dimensional Casimir Effect one could encounter the Harmonic series, which does not converge. By manipulating this series one can derive a convergent series (where the expression 1/12 might pop up) corresponding to measurements. The magic here could be interpreted as the effects of virtual particles. Or more or less as I "understand" it. Pop science keeps pushing the notion, but I suppose a physicist might also. This is strange territory where philosophy can't seem to abstain trespassing. :chin:

  • A first cause is logically necessary
    When one forms a causal chain mathematically, one can assume that at each step a single causal function exists. But in the real world a host of causal "forces" may be in play at each step, and somehow they must average out to prolong the expansion. Here is an attempt to corral those forces in the simplest mathematical structures.

    Note that this looks at causal expansions starting at an original cause and moving forward through time.

    As much as I can recall this is a true story, perhaps inaccurate where my memory fails. He and I were bouldering companions while I got my doctorate and he got his masters at the same institution. We would go climbing together two or three times a week around 1970. At least at that time there were some real differences between the religions. However, the Catholic Church has moderated a bit over the intervening years.

    I haven't talked with him in years. But I see EWTN has a fairly recent hour long interview with him and his wife. They were Pentecostals before Catholics, I see. He worked with a Watergate conspirator turned preacher at some point.

  • I’m 40 years old this year, and I still don’t know what to do, whether I should continue to live/die
    A long time ago a good friend of mine, a young man at the time, inhabited a world that was falling apart - or so he perceived it. He had no job, despite an advanced degree in the sciences, his wife threatened to leave him and take their two small children. He was at wits end.

    His wife, a devout Christian, insisted on him joining her father's church (her father was pastor), or she would leave. He gritted his teeth and joined the church - and focused on acquiring the "belief" upon which the church was founded. In other words, he told himself, "You will believe what they believe".

    Some would say, You can't believe something you don't believe down deep - it will always be a superficial belief. But my friend would prove them wrong.

    He not only came to strongly believe the faith, he became a missionary, working with prison inmates along the Gold Coast of Africa. He spoke with President Reagan about his work.

    Now, here is the truly odd part of the story. His church was protestant, and my friend wrote published articles about the dangers of Catholicism. Then, one day, he and his wife and family converted to the Catholic faith, and he became a Deacon of the Church, working with the homeless.

    If you make up your mind to believe, it's not an impossibility. And it's a possible way out of your dilemma.
  • Time travel to the past hypothetically possible?
    If one looks at a kind of causation chain that has taken one from birth to the present, at each temporal step a host of causes converges to form the next step, not an easy thing to grasp. Stanislaw Lem had an Ergodic theory of history in which going back in time and performing an act wouldn't necessarily cause a radically different present. The fact that so many aspects of causation go into effect for a moment might mean that they "average out" and any one might have very little effect compared to the others.

    The Grandfather paradox might not be completely binding. Give it some thought.
  • Donald Trump (All General Trump Conversations Here)
    Trump appears to be in the mold of Mussolini - the arrogant stances and stern facial imagery. Back then the Italian people wanted someone to come in and bring order out of chaos, and he did, at least for awhile.

    I wouldn't be giving Trump a second glance if it were not for the imbecile who is president now and the way he opened the borders of our country and allowed hundreds of thousands to migrate here non legally. I suspect the reasoning was to flood municipalities with people who would probably vote Democratic at whatever levels they could. Cities, counties, perhaps states. This might shift the House into Democratic hands. Non-civilians voting in national elections is problematic.

    The irony is that the big Democratic sanctuary cities are losing high income tax payers to be replaced with homeless and welfare subjects.

    Don't pay any attention to me. I'm old and doddering, the third stage of the Riddle of the Sphinx.
