Introduction. The relevance of «practical philosophy» is contrasted with «traditional philosophy», detached from life. The final perspective sees the harmonization of theoretical-practical and practical-theoretical activity of philosophers, based on the appropriate historical and logical rethinking of the history of philosophy. The classical beginning is to emphasize the practical component of early Greek philosophy. Theoretical analysis. The direct connection to life unites Thales as a sage with Thales as a philosopher (the widespread idea of the remoteness of Thales' philosophy from practice is criticized as being engaged by the dominant theoretical-practical paradigm of philosophy). The expert model of the practical component of Thales' philosophy generally characterizes the Milesian school and the Eleates. The absence of effective philosophical practice contributes to the skepticism of Xenophanes and the tragic nature of Heraclitus' work. Political activity of Pythagoreans is the objective maximum of the practical component of philosophy (political model of the practical component of philosophy). The problematic nature of philosophers' political activity, the growth and complication of theoretical research lead the ancient atomists towards the formation of a theoretical-practical model of philosophical activity. Conclusion. The problem of connection with life was positively solved in the work of Thales and was significant for all early Greek philosophy. This should be taken into account in the further study of the history of philosophy; the latter is in essence the school of thought that contributes to the harmonization of theoretical and practical activities of modern philosophy.
