Think deeply about your world view

Think deeply about your world view.

  • A good world view enables one to achieve a greater understanding with less work.

  • Ineffective world views are ultimately replaced by more effective ones (in the sense of a scientific revolution, but the process is not necessarily that dramatic).

  • If you cannot identify factors that have influenced your world view, you probably do not have one.

Typology of a Scientist


My world view

My World View

Natural selection is the primary process by which evolution proceeds; over long time scales, this process occurs most strongly at the level of the individual (or below). Macroevolution is merely microevolution over a long period of time.


My world view1

My World View

A proximate cause must be known before an ultimate cause can be identified because proximate (behavioral, physiological, or developmental) processes determine the costs and benefits of phenotypes.


My world view2

My World View

A general theory can explain phenomena in the majority of cases. Such theories are bound to be complex because ecological and evolutionary phenomena stem from multiple causes.
