# Are the amount of thoughts that a brain could potentially produce finite?

Using the fact that the brain is basically a finite entity(finite neurons, synapses, neurotransmitters, etc).

If we have a brain that:

• Doesn't run out of energy
• Never dies
• The brain uses a finite amount of senses to take data from the universe(vision, smell, touch, etc).
• The brain could use its finite senses to "explore"(take data) from any part
of the universe.
• The universe where the brain exist is a finite universe(finite input that
the brain could possibly expose itself too).

It is fair to conclude that the brain described in this scenario can just produce a finite amount of thoughts(I'm assuming that a "thought" is a particular computation[change in state produced by the brain itself] that the brain could make.)?

• Does the finite universe conform to thermodynamics as we understand it? Any computing device requires energy to run, so ultimately the answer hinges on the energy available over time. – Asher Oct 15 '17 at 1:46
• Lets assume that the brain never dies or runs out of energy. – user63152 Oct 15 '17 at 1:52
• Could you also clarify what counts as a "thought?" We already have infinite non-repeating outputs (the decimal value of \$pi \$for example) but I wouldn't consider that as a sequence of thoughts. – Asher Oct 15 '17 at 1:57
• Can you go through and explain the terms that you're using, for example how "finite universe" is equivalent to "finite input". Does the entire universe input into someone's brain? What does that mean? Most of the time when someone says "finite universe" they're talking about the total volume of the universe or the length of time that it will exist, I'm not sure what that has to do with input into the brain unless you're measuring the amount of time the brain can exist. – Not_Here Oct 15 '17 at 2:05
• If what you are asking is really "if a brain can think one thought per some amount of time and it never runs out of energy or dies, is the total amount of thoughts it will produce finite or infinite?" I still think that is a very not well defined question because it depends on a lot of complexities of what 'thought' means, but let's take that at face value, you're basically just asking "if I start at zero and add one per some time interval, will my final number by finite or infinite?" – Not_Here Oct 15 '17 at 2:07
