Buddhism and a persisting self

I recently read the following article:


What the Buddha Didn't Teach About Reincarnation

It says:

"This is not to say that “we” do not exist–but that there is no permanent, unchanging “me,” but rather that we are redefined in every moment by shifting impermanent conditions".

This appears to me to be just the same as what materialists are obliged to believe.

"Suffering and dissatisfaction occur when we cling to desire for an unchanging and permanent self that is impossible and illusory".

How do they know this? I agree it is liberating to believe this. For example, our fear of death is misplaced since we are effectively "dying" every infinitesimal fraction of a second anyway. And our everyday concerns are also misplaced. Such a philosophy, if wholeheartedly subscribed to, will lead to tranquillity, acceptance, loss of fear about all things.

However, this philosophy denies an *I* or you, or self. No reason to fear anything, but also it robs one's life and the existence of all things of any purpose. There is no point in planning ahead. It makes everything we ever do, pointless. It is, in a sense, a life denying philosophy.
