The Nature of Truth
It can be discerned that there are two basic kinds of truth: the transient and the transcendental. Transient truths were not always so, they can be changed and eventually they will cease to be so. For example if someone honestly said that there is a tree growing in their garden then that would be a transient truth: it was not always so, it can be changed and eventually it will not be so. Transcendental truths are eternal and immutable: they have always been so, they were not created by anyone, even God. They cannot be changed in any way and they will always be so forever.
An example of a transcendental truth is 2+2=4. However the realm of mathematics is not made up merely of sums. Take the so called cannonball problem for example: Find a way to stack a square of cannonballs laid out on the ground into a square pyramid (i.e., find a square number which is also square pyramidal). It turns out that of all the infinite integers only integer 1 and integer 4900 are both a square and a square pyramial number. This illustrates that "number" contains many surprising patterns and interconnections and the patterns and connections are absolutely eternal and unchanging. In other words they are sacred, they are holy.
Behind our more or less arbitary symbols and language exist timeless mathematical truths from which all more transient truths are derived. The language that we use to describe truth is itself based in essence on transcendental mathematical truths.
Truth can be roughly categorized in a hierarchy from unchanging mathematical properties at the top down to trivial transient "facts" at the bottom. The lower/more particular conforms to the higher/more universal. Here is a run down of the basic levels in the hierarchy as concerning the main sciences:
The first level consists of the truly universal laws including the laws of mathematics. We can see this levels relation to physics:
Physics is based on mathematics (mathematics does not rely on physics but physics does rely on mathematics) so it is placed below it in the hierarchy but it is the basis of the other sciences/all material phenomena so it is placed above them.
Chemistry is based on physics so it is placed below physics but chemistry itself is the basis of biology so it is placed above it.
Biology is based on chemistry so is placed below it in the hierarchy.
Lower still in the hierarchy are transient facts such as names, position and state of objects.
Do not be deceived into believing that all opinions are of equal value, that you cannot know the truth, that no one knows or that truth is merely a shifting and relative opinion. There ARE universal transcendental truths and only by accepting this do we have a chance of making real gains in understanding and thus overcome the tyranny of ignorance and confusion.
It seems convenient for many to believe knowledge of real truths is not possible because that imagined scenario allows them to justify their laziness and lack of healthy concern and curiosity for truth. Do not let such people hold you back but stive owards with determination.
Some people cherish their own beliefs and opinions to such an extent that they ignore direct evidence to the contrary. They are not really interested in the truth as much as they are in defending their own beliefs. Such people fear the truth and often labour under thousands of negative and crippling attitudes and beliefs their whole lives leading to needless suffering.
The other type of person is loyal to the truth- whatever it might be- over their own beliefs etc. Such a person is humble
enough to realise that they don't know it all and has a natural curiosity about the world around them. If someone like this is
proven wrong, they are not defensive: in fact they are delighted for it means they have moved closer to the truth.
If you wish to know the truth then rigorous self honesty is a great aid: If you want the truth be truthful. Deep honesty will atune you to deep truth-deepest honest will atune you to the deepest truth.
You are eternal and so is truth. Your particular inclinations for and against different aspects of truth can only be temporary and will inevitably stabilize into universiality. You can help the evolution of your consciousness by contemplating the nature of truth.
