ZD, you really like that topic, don’t you.
Jabotinsky was not a leader. He was an activist of the type that it is not surprising that he had extreme expectations. People today also predict all sorts of things. When one of them turns out correct, does that make him more on target? No.
The Mishna says, ????? ???? ??? ??????. Does giving an Eitza mean you have absolute knowledge? It means you know how to make a decision. I hope this is not too deep for you.
I usually decide things with my head rather than my heart. If it turns out that my heart was right and not my brain, should I start following my heart and ignore logic? If I read wrong should I stop reading?
These are actually two separate things. It is worth speaking things over with a wise person and since ????? ???? ??? ??????, a Talmid Chochom that learns Torah Lishma is the best candidate for that. Another issue is community questions. The Chachamim are the Einei Ha’eida and must be listened to in these matters. Those who don’t listen are Poresh Min Hatzibur. There is also a Siyata Dishmaya to help make decisions in these matters, as it says, ???? ????? ???????.
Additionally, there is a Seyata Dishmaya in advice from a Talmid Chochom who learns Torah Lishma and is Dover Emes Bilvavo. There is also a concept of Ruach Hakodesh, which is why people turn to Gedolim for personal issues.
