bais yakov maidel,
If contemporary hashkafa books don’t do it for you, then write your own.
BTW, hashkafa means to “look down” (Rashi on Chumash). That is to say that one is above and can therefore intellectualize and judge what they are seeing when they look down. To me hashkafa also means condescension, as people make their philosophies to match their actions and feelings (Ain adam maiseem et atsmo Rasha – B”K 3a – I think). People can then judge others by those philosophies. If I judge with my hashkafa, I always come out good but others maybe not so good. And on it goes from person to person, Rebbe to Rebbe, and group to group.
An example: A while ago, I was in shul and the Rav was teaching a hashkafic idea (I don’t remember). His son, who is in Kollel, clearly disagreed with him. The son thought that the hashkafa was not in line with fruimkeit. Afterwards, the shul Rav showed his son the sefer that he was quoting from, which was from the Rambam. And no, it was not from the Moreh Nevuchim, nor was it anything controversial. But it was not shtark enough for this kollel man.
I don’t see the requirement for hashkafa. I happily do mitsvot because I am supposed to because Hashem said so. Could I have an intellectual or philosophic reasoning that explains the mistvot to me? Yes, but that’s not required, nor should I think that my reason for anything is The reason. It’s just to motivate me. If you need some ideas to get you motivated, either keep looking, or just write your own.
