If Plato in the Republic means the ideal city to be an analogy for the human soul, doesn't this imply that the human soul too inevitably degenerates into barbarism as the city does?

I mean, if there is something inherently defective in the rule of the Guardian class which leads to a collapse into tyranny, isn't Plato implying that it is therefore impossible for human reason to control our appetites? And if so, wouldn't that make the pursuit of justice, knowledge, the Good and so on futile?

How might Plato have responded to this objection?

I think Plato would've said that a philosopher's soul, or a soul ruled by love of knowledge, is the only soul that is able to self-care in a way that doesn't make it barbaric, and that a non-philosophical soul can be tyrannical towards itself.
