A sensible judge would wish to be satisfied in regard to the third statement before wasting time discussing the others; if it proved to be true, then the case would be at an end.

The defences of philosophical systems are often similar, and the critic is tempted to waste time discussing details when he should go to the root of the matter.

Eucken does not fall into this error.

His special method is to seek the idea or ideas which lie at the root of the proposed solution; if these are unsatisfactory, then he does not consider it necessary to discuss them further.

Hence his work is free from the flippant and superficial argument so common to-day; he makes a fair and serious endeavour to find out the truth (if any) that is at the basis of the proposed solutions, and does not hesitate to give them their due meed of praise even though he considers them to be ultimately unsatisfactory.
Before a solution can be regarded as a satisfactory one, Eucken holds that it should satisfy certain conditions.
