Happy to help.
First question: My question is, do spiritual people really care about others' opinions of them?
Answer: Spiritual people don't usually care much about what people say about them. The problem comes when being spiritual is a clear disadvantage. Example: Many people do not get support for their spiritual business ventures because other more rational people do not take them seriously.
Second question: I'm confusing spiritual people with stoics. However, can you please give me a short definition of what a spiritual person means to you?
Answer: Stoic philosophy focuses on living a good virtuous life by avoiding anguish over things you can't control (very short).
Spirituality focuses on transcending life.
The main difference is the belief in the afterlife: the unknown, magic, divinity, your vision of what happens after death, etc.
Marcus Aurelius gives you advice on how to live a good life.
Jesus tells you what to do to reach eternity after death. He urges you to surrender your pain to the cross by embracing it, contrary to stoicism or hedonism among others.
Nevertheless a philosophical system X or Y can be central to spirituality as in Buddhism or the Christian system of morality and ethics.
Theology used to include philosophy in the university. Then they began to be taught separately. In the same way that at the beginning of the last century psychology, which was part of the philosophy course, began to be studied as an individual course.
A philosopher can be spiritual if he believes in the beyond, in the magical (so to speak), in the unknown, in divinity (according to whatever his spiritual tradition is, whether organized religion or individual belief). A spiritual being cannot be spiritual just by being stoic; if he does not believe in the beyond, in the unknown, in the subtle.
The word philosophia comes from Greek and means love (philo) of wisdom (sophia). And wisdom is only one of the seven gifts of the Holy Spirit (wisdom, understanding, counsel, fortitude, knowledge, piety and fear of God).
In conclusion: philosophy may be part of spirituality, but spirituality encompasses more things.
I hope this answer, which is just my humble opinion, has helped you.
Have a great day mate.
