While 'Buddhism' suggests another belief system, 'dharma practice' suggests a course of action. The four ennobling truths are not propositions to believe; they are challenges to act.
Buddhism, I think, is probably facing the single most difficult transition from one historical epoch to another, which is really the transition to modernity.
A secular approach is not a dumbing down, it's not reductively identifying Buddhism with one or two particular techniques of meditation, but it is actually a complete world view and way of life in this world.
The Four Noble Truths are pragmatic rather than dogmatic. They suggest a course of action to be followed rather than a set of dogmas to be believed. The four truths are prescriptions for behavior rather than descriptions of reality. The Buddha compares himself to a doctor who offers a course of therapeutic treatment to heal one’s ills. To embark on such a therapy is not designed to bring one any closer to ‘the Truth’ but to enable one’s life to flourish here and now, hopefully leaving a legacy that will continue to have beneficial repercussions after one’s death.
