Everything we hear is an opinion not a fact

What do the senses tell us and how to relate it to the Intellect (nous)? In this higher, metaphysical, order there is only one (ultimate) truth: that arrived at through contemplation of ‘Ideas’, themselves reducible to the one supreme Idea, ‘the Good’. This is the only thing that merits the name of real knowledge according to Plato, and is not transferable from person to person.

Questions that are well-defined have answers that are more "true" than questions that are less well-defined. 1 + 1 = 2 is very well defined; the meaning is exact, and it is only meaningful if you accept all the initial assumptions that precede it (things like the definition of an integer, what addition actually means, etc). The other 99% of life is much more poorly defined, and often the initial assumptions are themselves in dispute. "I was fired because my boss hates me" is an opinion, rather than a fact, even if it seems stunningly obvious, to me. My boss will likely have a different view I am sure.

I believe he's addressing these comments as general advice about practical matters, rather than asserting that facts don't exist at all. A stab through the heart is a dangerous wound, and I don't think he'd ever doubt that as a fact. All interactions between people can be considered at most ‘true opinion’ (except, as said, consensual, empirical truths for the most part). Plato found ‘true opinion’ to be lacking in epistemic support; in the end he even made a joke about it, rather than ending with the usual ‘aporia’ (indeterminable). A similar account of truth v. belief or opinion can be found in Eastern metaphysics.

The world will do everything you fear or desire whenever it wants. Yet amidst life’s volatility, your inner character & mind act as continued sources of stability. Life is fraught with hard decisions, which imbues many with regret of alternative paths. Duty & ambitions are imperative, but find solace within the internal mind, not external results. Given you leveraged your full internal arsenal, the world can’t ask more of you.

Generally speaking we’ve got facts, beliefs and opinions with us. Most the time we mash them all together and we make beliefs facts or opinions, beliefs or facts or false beliefs and so on and on. And we do this because we pass on information to generation within our own communities and families that may not actually be a fact but has become one over time due to the information downpour. Similar to the telephone game if you've ever played.

We also tend to believe that facts are concrete and permanent when they're not. They are fluid and subject to change often so a fact is something we know right now to be true it doesn't necessarily mean they will remain fact, a classic example is today we know that the world is not flat but once upon a time we believed it was flat and that was fact, and any one who thought otherwise was crazy.  Also believe that a fact has a little bit of belief and a little bit opinion thrown. I think that we've just intertwined all of them that the answer to your question is maybe.

Maybe of course at some point a fact was an opinion or and an opinion was created from a belief and at some point that belief could've been a fact, you know? The only reason why Columbus was given the ability to find out that the world was not flat was because the Queen had a crush on him otherwise he would've been hanged for being mad. This thing is we need beliefs indeed need opinions and we need fact but we also need is to learn how to think critically and be able to distinguish between the three. Cheers!
