@otto:
What's tabula rasa?
And I'll rephrase:
In our MINDS it is a blank slate right now, we're trying to BUILD the idea of existance from scratch, from the basest ideas, and moving up.
And I'd put foward this:
All knowledge that we can logically attain is derived from the senses, or that's my position at the outset here, and all of those are faliable.
SO we can't know ANYTHING as of yet.
HOWEVER, recall FEELING.
I mean internal feeling, such as feeling sadness or happiness.
Now, generally speaking you might say at this point "Well, that depends on knowledge of what your are upset about or what you are happy about" to which I respond, "Yes, but you HAVE those concepts at the start, in their most basic form, and nothing is required to give you those. For example, anyone and everyone, no matter how intelligent, dumb, strong, or disabled will KNOW what happinesss or, at the very least, pain and sadness ARE... they may not be able to articulate those feelings, but they will know what they are, they are inborn features that all human beings have."
So I posit that THIS is the first block in our interpretation of the Universe:
We feel and know at least basic feelings, and from THIS we derive ideals that FIT those feelings, preferrably to strengthen them (ie, we form the idea of the five senses from our wanting something "happy" to see, taste, touch, etc. and also here we might find religion, as that may make us feel happy to feel "protected" as it were... and for negative feelings we again have the senses, and from those such things as stubbing your toe to feeling a bullet hit your chest, and here, as sadness and pain are negative, we get the opposite of the religious Deity, which would be Sin/Devil/Something Upleasant to Cause us Pain.)
