Is it reasonable to believe that which is true?

[Tree of Life]

Not unless there is a reason to believe that it is true.

There is a Firschizleschmocks living under my kitchen sink.

Since I can't prove there isn't a Firschizleschmocks living under your sink, should it be assumed you are correct and don't need any additional evidence to convince others of your claim?

 

[Hank]

Let's say it's true that the Firschizleschmocks exists. Merely because it is true that the Firschizleschmocks exists, is that enough to make it reasonable to believe that the Firschizleschmocks exists?

No.

If Firschizleschmocks exist, as in proven fact, they simply exist. Belief is irrelevant here for a true or false classification.

If you equate Firschizleschmocks to something like True Love, a none tanglible entity, belief in it is a prerequisite. And this opens a can of worms debating if it even exists or not.

 

[Songsmith]

It begs the question of how (or whether) you know that something is true. But yes, it's reasonable to believe things that are true.

I'm pretty sure that this is the basis of philosophy in the first place. Differentiating (or trying to) between that which can be known and that which is believed.
