… But there is a real possibility that the universe is not objective, at least not in the way we think it is.
As soon as you append “
in the way we think it is” to your sentence, you are no longer describing the objective universe, but instead are referencing our
subjective beliefs about the objective universe. What we as
subject believe about the
object called the universe does indeed vary from person to person (i.e. is subjective). However, by definition “truth” is “that which corresponds to reality” (Webster’s). “Reality” is “the body or set of all real things.” “Real” is that which is not “illusory, false.”
So it seems, according to our language and the ideas they respresent, that “truth” is “that which corresponds to reality” and it is indeed *objective , *meaning it does not vary from person to person as does “belief”.
For example, if I’m color blind and due to a genetic defect cannot properly distinguish the wavelength of light which reflects off objects, that doesn’t mean that the “real” or “true” wavelength of light reflecting off objects has indeed changed from objective reality. It merely means that as
subject I am less capable of sensing the truth about that which is
objective (reality). We have other means apart from our eyes to detect the wavelength of light reflecting off of surfaces, so in this instance, we can scientifically verify that what I sense
subjectively is not true according to
objective reality. Simply put, if I close my eyes, it doesn’t mean that all the light stopped reflecting off of everything in the room.
It would be linguistic confusion to use the word “belief” as though it was the same thing as “truth”. They have different meanings for a reason, which allows us to better distinguish and express what it is we are talking about. From their very definitions, truth is objective, belief is subjective.
That one is compelled to partake in the act of breathing in order to live is not certain proof…
All of our
subjective beliefs derive from (1) reason, (2) experience, and (3) the testimony of others. This is true of
every belief in
every field of study. The one breathing, in your example, can only form his intellect using these three kinds of evidence. Nonetheless, his beliefs are always *subjective, *as they necessarily vary from person to person. They have a real possibility of being either true or false. This is because the ability to reason, the personal experience, and the varying testimony each has been exposed to varies from person to person. I suspect those with poor ability to reason, not much experience, and without having much trustworthy testimony tend to be easily deceived, tending toward beliefs which may not be true.
Yet, it seems all of us have this innate urge to subjectively believe that which is objectively true. In other words, we don’t want to be deceived. We don’t want to assent to that which is not true. All ought to seek to form their intellect such that we are less likely to be decieved, tending toward assent to what is objectively true (real), not to that which is not real, illusary, false, deceptive.
…quantity called “oxygen”. It is merely evidence…
Yes,
objective evidence (i.e. does not vary from person to person). The fact that all of our beliefs are
subjective, all seeking to assent to that which is
objectively real, does not mean that reality is therefore
not objective.
In other words, just because my eyesight is not perfect (or perhaps reason, experience, and testimony are imperfect), doesn’t mean I do not see some things well enough to make certain rational judgments sufficient to remove doubt. We all must reason through or examine the preponderance of evidence before us, the various testimony and experiences we’ve gained, in order to determine for ourselves that which we believe to be true.
“Absolute certainty” is an impractical standard for assent. We all make decisions based upon incomplete or imperfect information. To do otherwise would impair progress, growth in all human endeavors. While some may stubbornly insist upon such an narrow epistimology in theory, that’s not their real human experience. In real life, people are constantly deciding matters based upon less-than-perfect information, based upon less-than-absolute certainty in every field of study including science, economics, sociology, politics, military studies, social relationship, etc. For one to apply such a epistemological standard for everything in real life, while at the same time theoretically demanding a more rigid standard for other things, such as religion or philosophy, is to live inconsistently, which is to say, without integrity.
It seems odd to need to defend such self-evident propositions that reality is “real” and the truth is “true”, but our modern tendency to confuse these terms and use them contrary to their customary useage makes such a thing necessary.
