The first essay can be said to represent Husserl early in his career, when he was seeking to gain a hearing for his radically new scientific manner of philosophizing. The second dates from the years immediately preceding the cessation of Husserls philosophical activity. Together they constitute a striking testimony to the continuity of Husserls scientific ideal in philosophy. The intervening years saw considerable development of the detailed method for attaining the goal of universal rationality, but it is significant that the position achieved as a result of this development in no way involved relinquishing any major position adopted at the beginning or along the way. Thus we have in these two essays on only an early in a late stage in the genetic growth of Husserls thought but also an introduction to what can be called his definitive attitude toward the very nature of philosophical thinking.
