When "it comes down to it," one would like one's philosophy to be true.  I don't think, then, that one can really say one chooses one's philosophy.  Rather one looks for the truth and then is obliged to go with whatever one finds, whether one likes it or not.

I often get, when describing some teaching or another, an "I don't like that."  My unspoken thought is, "So what? Whether you like it is not relevant, and thinking your likes and dislikes are at all to the point is just arrogance and foolishness."
