Even two people who speak the same language can never be sure that they are communicating perfectly the essence of what they mean. Meaning has something to do with experience, and each individual has a different experience of life. Different shades of meaning tone each person's vocabulary. Even if an outside mind could enter another mind, and directly read the information encoded there, it would not be able to extract meaning from it in the same way that the original owner of the information would, because the experience of the observer colors meaning. Although it is difficult to imagine, much less test, it is likely that the non-verbal forms of information that an individual's mind deals with would likewise be subjectively colored as far as meaning goes, and would evade precise reading by an outside mind.
Identical stimuli have variable attraction to different people due to differences in taste.
The reading of outside information always seems to call for some degree of interpretation on the part of the mind doing the reading, in order to capture meaning. If information evolved when DNA and life evolved, then before life there was no information. In that sense, matter and energy, in any of their forms and combinations, had an existence beyond any subjective interpretations we may make about them today. Let us call that existence, in that pre-life period, objective reality at that time. Whatever existed at that time existed beyond the need for any interpretation from us to define it.
