My long-term (continuous for at least 25 years) hobby is history, and I spent significant time in university and later studying philosophy. This has given me a rather conscious view of where my intellectual sympathies lie and why. Among the long-standing schools of thought, I feel most at home with the empiricists rather than with the idealists - the mysticists I just can't appreciate. This is, I tent to prefer Aristotle to Plato, Hume to Descartes, and shake my head sadly over Pascal. I find comprehensive "systems" like those of Plate and Kant fascinating, yet fundamentally unsatisfying in that they appear to me dangerously remote from everyday experiences and the essential peculiarities of individuals.
I find Kierkegaard's almost fanatical concern for the individual and keen psychological insights much more appealing than the grandiose schemes and concern for humanity in the abstract of Hegel or Marx. Respect for groups that doesn't include respect for individuals of those groups isn't respect at all. My C++ design decisions have their roots in my dislike for forcing people to do things in some particular way. In history, some of the worst disasters have been caused by idealists trying to force people into "doing what is good for them." Such idealism not only leads to suffering among its innocent victims, but also to delusion and corruption of the idealists applying the force. I also find idealists prone to ignore experience and experiment that inconveniently clashes with dogma or theory. Where ideals clash and sometimes even when pundits seem to agree, I prefer to provide support that gives the programmer a choice.
