Pure truth that communicates knowledge beneficial to humanity would have to come from a non-human source.
Humanity, you see, is incapable of knowing pure truth within its own experience of life, for humans are all corrupted by their selfishness and ignorance. If there was no outside source of truth and beneficial knowledge, we would only have our own source, which is always ruined by our selfishness and ignorance.
Take the realms of scientific knowledge and truth as an example. Although the Bible is not a book about science, it tells us at the start that "In the beginning God created the heavens and the earth." Most humans have decided to ignore that beneficial information and build their science base without it. Now, the systematic gathering and formulating of scientific knowledge is not a bad thing. Unfortunately, it is what some humans do with that body of knowledge that can, and has resulted in sometimes deceiving humanity, even to threatening our very existence on this planet. Remember Oppenheimer saying in dismay, “I have become the destroyer of worlds” when the atom bomb was used?
Let me now quote from the book below, written by a scientist: “Science has become political... Here is what Pandit Nehru, first prime minister of India said: “It is science alone that can solve the problems of hunger and poverty, of insanitation and illiteracy, of superstition and deadening custom and tradition, of vast resources running to waste, of a rich country inhabited by starving people.”
“In the half-century since then we have learned that science may achieve astonishing things, but arguably without political will it is powerless on its own to achieve Nehru’s dream. There is no technical reason why anyone in the world today should starve, go blind with cataracts, have no access to clean water or die of the many preventable diseases. Although science has delivered the knowledge to solve these problems, the wisdom to use it does not seem to come with the package...
“In the UK there was no stated political definition of the reasons for state funding of research until the White Paper of 1993: ‘The mission of each research council has been changed to meet the needs of users and to support wealth creation... thereby enhancing the United Kingdom’s competitiveness and quality of life.’
“We will see that this definition does little justice to the historical story of science. Very few of the great scientific discoveries would, at the time, have cleared the bar o meeting ‘the needs of users’ or supporting ‘wealth creation’. The White Paper mission statement also implies a very common confusion of the two very different activities of science and technology. But it does project onto the public screen an idolised view of science – in the sense that it is our idols that we perceive will deliver our ideals.”
“Radio producer and arts graduate Angela Tilby wrote in her book ‘Science and the Soul’ from the perspective
of someone with no background in science, yet attuned to the way it is projected: ‘Like priests in a former age, [scientists] seem to guard the key to knowledge, to have access to transcendent truths which the rest of us could never hope to understand. Many people feel that what they do is cut off from everyday life, that it is irrelevant and rather frightening, a form of magic.’ [quote ends]
Science is not a threat, but the way some people seek to use and abuse it (for selfish or financial or political gain) certainly does threaten humanity in general, and disguises other truth by twisting known truth - which is deception.
