Quote of the day by Heraclitus , “All things come into being by conflict of opposites,” offers a way to understand change, struggle and balance in life. Heraclitus argued that existence depends on tension between forces that appear to be different or opposed. Hot and cold, day and night, health and disease, joy and sorrow can be understood in relation to each other. His philosophy also focused on constant change and the idea that nothing remains fixed. His thoughts connect conflict with growth and show why difficult periods can change how people understand peace, success and happiness.
