Doubts should always exist, but they should serve as a path in establishing truths and knowledge. Isn't this the purpose of philosophy and the philosophers? — Alkis Piskas
I don’t think so. Establishing that the purpose of philosophy is establishing truths and knowledge means that these reference points will be treated as beyond dispute. But the history of philosophy gives evidence that the very existence of truth has been questioned since the beginning: think, for example, about the sophists, who tried to show how tricky our language and our thinking is; think about Heraclitus: if everything is becoming, then an established truth cannot exist, it will be becoming as well; think of Nietsche, who said that we don’t know where to go, there is no up, no down, no orientation. You might object that all these positions can be considered as efforts to establish truth: the truth that truth is becoming, or even the truth that truth does not exist. But this objection works like a closed system: closed systems works always, independently from their content. For example, it is impossible to question that everything is number, because such a system will be always able to answer that any objection can be traced back to a structure of numbers. This way, even saying that the essence of reality is, let’s say, tomatoes, or horses, is able to be an invulnerable system. For this reason, any invulnerable system is meaningless, because it is able to maintain anything and the opposite of anything. This means that the idea of truth itself is meaningless.
If he were always and constantly in doubt about everything, he would be a mentally ill person — Alkis Piskas
I don’t think so. I have adopted the perspective of doubting about everything for dozens of years now and I don’t think I am mentally ill: currently I work at a hospital and I don’t think they would allow a mentally ill person to work in my position.
if I live in a constant doubt, it means that I would also doubt that I doubt. Which leads to vicious circle — Alkis Piskas
Doubting of doubting is not a vicious, but a virtuous circle: it is a circle that reinforces itself, similar to certain phisical phenomenons, like the audio feedback effect in microphones. Doubting of doubting just confirms that I cannot trust anything, I cannot even trust my doubting. Not trusting my doubting means just that I cannot rest firmly and comfortably in a simple methodology of doubting: I need to always question my questioning as well. Where is the problem in this?
And then of course to an asylum — Alkis Piskas
I agree that we need some kind of asylum, but not because of any philosophical principle. We need some kind of asylum because we are humans, we are not machines, we get tired, our emotions need to find some kind of rest on something. But, since this is not a philosophical, but a human need, the solution is not any philosophical thought, but some practical instruments, like periodically going to bed, having experiences of love and friendship, having a home, or a tent, having periods of rest.
A persons's reality may include doubts but it cannot be built on doubting evertyting. It is mainly build on knowledge and certitudes — Alkis Piskas
I think here again you confuse philosophical with human needs. If I go shopping, I cannot answer the teller “You don’t know if the things in my bag exists, you don’t know if my money exists”. I just need to pay. But this is a human and practical need, not a philosophical one. Practically I need just to pay and not to create problems to the teller, but all the doubts I expressed are true (I know I used the word “true” now, but this is needed by language, not by philosophy).
There is a solution that is better than certitudes and knowledge, that actually are very misleading concepts. The solution is trust. Although everything is exposed to doubt, my being human forces me to trust a lot of things and people. So, I pay my money to the teller not because I have any certainty that my money or the teller exist, but because my human condition forces me to trust some practical assumptions and treat them as if they were something “true”. I don’t “know” if fire would burn my hand, but my human condition forces me to treat it as if it was something true.
This is (pace those people here who want me to be severe, exact and giving strict evidence of my statements
:grin: ) Heidegger: being does not exist; being is our human condition of being immersed in time, in our needs, in our mental limits.
