Alexander the Great influenced the scientific revolution of the 3rd Century B.C. His dominance is connected with three of Alina Motycka's determinants: abruptness, immediateness, and completeness. Alexander influenced the human unconsciousness in ancient culture by the archetype of the king. Macedonia became patron of science. The scientific discoveries were used by Alexander the Great in his wars. The Macedonian King was highly educated. He knew the importance of knowledge in human life. The difference between 'tekhne' and 'epistéme' gained a special meaning. At this time, Stoic and Epicurean philosophy had appeared. The happiness of a person became the most important problem of philosophy. Many great centers of culture and science, e.g. Alexandria founded by Ptolemy, came into existence as an effect of the reign of Alexander the Great. According to Irena Kodisowa, Alexander became the precursor of a new epoch in ancient culture - the Hellenistic epoch. His dominance changed the ancient world forever, however this change took up so many sacrifices, that its creator was rejected for a long time by his contemporaries. .
