Philosopher John G. Bennett proposed the idea that there are actually three time-like dimensions, in addition to the usual three spatial dimensions.

I would be curious to learn what the philosophical implications of such ideas might be, and whether there are any new advances or ideas in this area. I would be most interested in implications that might affect our physical understanding of the world.

Is there any evidence that this is worth discussing--that there might be two more time dimensions in the way he suggests? I can always invent something and ask what the philosophical implications are, but given all the actual things that we might want to know about, the imagined ones ought to either be really profound or at least somewhat likely. – Rex Kerr Nov 4 '12 at 17:05
Actually there is a lot, because there will be a huge physical implications out of that and it's steadied not once by scientist... you may read Wikipedia article on that.. – TMS Nov 4 '12 at 19:03
I already did read the Wikipedia article. From there it sounds like, "He made it up, stated without mathematical proof what some of the properties are, and didn't say how to measure it." That is not very encouraging. I was hoping you had more insight into its potential validity. – Rex Kerr Nov 4 '12 at 19:38
I can provide you with more researches done by theoretical physicists on this matter, but unfortunately one needs PhD. in math or physics to understand them, for a simple article, please check phys.org/news98468776.html – TMS Nov 5 '12 at 15:04

I wonder whether the idea is worth discussing. Maybe dualism is false--maybe there are three substances (or ten!)! Maybe there are a continuum of souls. Maybe photons are one aspect of a true subatomic particle that gives us will. Maybe our consciousness is each linked to that of a unicorn in a shadow realm. What are the philosophical implications? (Do you see the problem with asking for philosophical implications without first an indication whether the proposed idea might be true?) – Rex Kerr Nov 5 '12 at 16:10

I'd suggest that this is simply mathematical/theoretical physics speculation, which is fine for what it is, but its physical relevance is irrelevant: We simply do not know what it means to experience two dimensions of time, let alone three.

One of the physical insights that Einstein provided was that we should consider space and time together, of course this is an old idea, but he showed that time can be converted to space and vice-versa, which was new.

The origin of the arrow of time is an interesting phenomenon, even if time is one-dimensional. The basic physical laws are essentially reversible, yet the time evolution of our universe is obviously not reversible. (One potential "solution"/"explanation" would be an "initial state" with a very low entropy.) However, what will happen to the arrow of time if time is three dimensional? – Thomas Klimpel Jan 19 at 12:35
