Jim,
Yes I am certain and I certain about that.
Actually, I am not entirely comfortable with number 6) - the 2nd law of thermodynamics - we may understand the message, but the problem is the necessarily arbitrary definition of "isolated system". Is it really isolated or is it part of a cycle - see the Entropy thread and all the structures in the universe for an additional counter-argument.
Number 5) could initially be interpreted as a semantic definition. This is due to the contemporary dogma that is unscientifically content to assign the unknown or invisible to magic, but then to justify it by given it a name: "of course it isn't magic, this is science, the force is caused by
the field". Somehow, it is dismissed and forgotten that force at a distance is impossible. Something must be causing the forces associated with the "field". I find it amusing that so many are able to poke fun at Einstein's curved empty space and then in the next breath freely accept that action at a distance is allowed. The field must be caused by something, therefore we may say that that something is matter. In times past you may well of been able to find the argument that air was not matter, but a mystical force. How little attitudes have changed. Regardless of those not able or willing to follow the logical argument, 5) is certainly true. In a way you could say that 5) takes 1) to 4) and using them as proof that invisible fields must simply be invisible matter.
1) to 4) are beyond logical reproach and indeed without them we are certainly lost.
Can you be certain you are correct if that belief does not fall under one of your six categories of things you are certain are true
Crafty, but to quote myself:
First of all, I would like to avoid any philosophical skulduggery that leverages the doubt of our fundamental existence. For sure we do not know the precise nature of our "consciousness". Also, perhaps we are living a matrix-like existence inside an alien supercomputer, maybe we are a dream within a dream within a dream. All quite possible, but all unprovable and all irrelevant to this discussion. We must assume that we exist as individual humans, on a planet, in a solar system, in a galaxy, in a galaxy cluster, in the universe.
We must surely assume that the physical process that evolution has provided to "allow" thought, also relies on the certainty of at least 1) to 5) and probably 6) too. In fact, I am certain of it.
