History serves an important role, but it shouldn't be presented as a laundry list of facts and dates. History is important in context, and the cause-effect relationships between events and the fallout/outcome of those events is the important aspect of a solid history lesson.
Unfortunately, a lot of history classes fail miserably in providing context for events. And, by context, I mean providing a survey of all aspects of life at the time. It's not enough to say "On so-and-so date, this happened. Next year, this happened, and ten years later, this happened. Moving on to the next century...."
What is needed is an understanding of all aspects of the social and cultural climate of the time. These aspects provide a why for the how, and by critically comparing various aspects of popular belief, social mores, cultural expectations and the like of the time, can there even be an understanding of what the causal relationship between event A, event B, and outcome C even is. Events need to be examined through various lenses, not simply associated with a number. And, ideally, these lenses include examining philosophical explorations or norms of that time as well. History is mildly interpretive, but as long as multiple viewpoints are broached and a solid contextual grounding is provided, History is certainly a very important foundation in being world-aware and grounded in the relationships of causation and outcome.
Philosophy is indeed also important, but really, any Literature surveys or humanities programs worth a damn will do a study into philosophy during the course of its program. Actually, through the simple act of critically examining a group of authors from a certain period of time or movement in literature provides a basic understanding of the philosophical underpinnings of the time. Philosophy is also extremely mutable and highly interpretive.
Ideally, there is no one or the other, but both, as opposed to an "instead" mindset, it's much more important to take both disciplines and explore them in their "wholeness," deciphering how one relates to the other and how they have interchangeably shaped each over time. Then a real understanding of our human past begins to take shape.
One without the other is a part and parcel education. It leaves holes in our consciousness like so much emptiness in a block of Swiss cheese.
